February 28, 2012  The editors of the APS journals have selected 149 new Outstanding Referees for 2012, out of more than 60,000 currently active referees. Initiated in 2008, the highly selective Outstanding Referee program recognizes scientists who have been exceptionally helpful in assessing manuscripts for publication in the APS journals. Selections are based on two decades of records on the number, quality, and timeliness of referee reports. The 2012 honorees come from 31 different countries, with large contingents from the US, Germany, UK, Canada, and France. The decisions were difficult and there are many excellent referees who have yet to be recognized. By means of the program, APS expresses appreciation to all referees, whose efforts in peer review not only keep the standards of the journals at a high level, but in many cases also help authors to improve the quality and readability of their articles—even those that are not published by APS. For more information and a sortable listing of all Outstanding Referees, please visit http://publish.aps.org/OutstandingReferees.

September 29, 2011 A primary goal of Physical Review C is to disseminate nuclear physics knowledge to research scientists working in the field. As a component of that effort, each published paper should carry a thoughtful, well organized abstract that conveys the main elements of the paper including the pertinent results.

July 26, 2011  The Niels Bohr Library and Archives is pleased to announce that it has digitized the complete Samuel A. Goudsmit Papers
(1921–1979, 30 linear feet, approximately 67,000 images). The Goudsmit Papers are a major international collection of correspondence, research notebooks, reports, World War II science documents, and other material of Goudsmit, a Dutch physicist who spent most of his career in the US and was involved at the cutting-edge of physics for more than 50 years. Goudsmit became Editor of Physical Review in 1951 and was responsible for launching Physical Review Letters seven years later. In 1967 he was named APS Editor-in-Chief.

June 6, 2011 The American Physical Society is pleased to announce a refresh of all PDFs contained in the scanned portion of our Physical Review Online Archive (PROLA). APS was one of the first publishers to put our entire backfile online, completing the scanning process in May 2001. In those early days, APS opted to put our content online quickly and in an inexpensive manner that would then allow us to take advantage of any future improvements in technology. We have now completed the next step by partnering with Aquaforest. Using their Autobahn DX conversion software, we have efficiently reprocessed our entire scanned archive of approximately 250,000 articles, further compressing them and adding searchable text. Researchers will find these enhanced PDFs faster to download and much more convenient to navigate and read. APS is committed to ensuring the long-term availability and usability of all of the information that we publish. More News/Announcements

This article reviews many manifestations and applications of dual representations of pairs of groups primarily in atomic and nuclear physics. Examples are given to show how such paired representations are powerful aids in understanding the dynamics associated with shell-model coupling schemes and in identifying the physical situations for which a given scheme is most appropriate. In particular, they suggest model Hamiltonians that are diagonal in the various coupling schemes. The dual pairing of group representations has been applied profitably in mathematics to the study of invariant theory. Parallel applications to the theory of symmetry and dynamical groups in physics are shown to be equally valuable. In particular, the pairing of the representations of a discrete group with those of a continuous Lie group or those of a compact Lie group with those of a noncompact Lie group makes it possible to infer many properties of difficult groups from those of simpler groups. This review starts with the representations of the symmetric and unitary groups, which are used extensively in the many-particle quantum mechanics of bosonic and fermionic systems. It gives a summary of the many solutions and computational techniques for solving problems that arise in applications of symmetry methods in physics and which result from the famous Schur-Weyl duality theorem for the pairing of these representations. It continues to examine many chains of symmetry groups and dual chains of dynamical groups associated with several coupling schemes in atomic and nuclear shell models and the valuable insights and applications that result.

The last decades brought impressive progress in synthesizing and studying properties of nuclides located very far from the beta stability line. Among the most fundamental properties of such exotic nuclides, the ones usually established first are the half-life, possible radioactive decay modes, and their relative probabilities. When approaching limits of nuclear stability, new decay modes set in. First, beta decays are accompanied by emission of nucleons from highly excited states of daughter nuclei. Second, when the nucleon separation energy becomes negative, nucleons start being emitted from the ground state. A review of the decay modes occurring close to the limits of stability is presented. The experimental methods used to produce, identify, and detect new species and their radiation are discussed. The current theoretical understanding of these decay processes is reviewed. The theoretical description of the most recently discovered and most complex radioactive process—the two-proton radioactivity—is discussed in more detail. [Rev. Mod.

We demonstrate that the high-quality cooling data observed for the young neutron star in the supernova remnant Cassiopeia A over the past 10 years—as well as all other reliably known temperature data of neutron stars—can be comfortably explained within the “nuclear medium cooling” scenario. The cool... [Phys. Rev. C 85, 022802 (2012)] Published Mon Feb 27, 2012

We present a systematic study of the effects from initial condition fluctuations in systems formed by heavy-ion collisions using the hydrodynamical simulation code NeXSPheRIO. The study was based on a sample of events generated simulating Au+Au collisions at center-of-mass energy of 200 GeV per nucl... [Phys. Rev. C 85, 054909 (2012)] Published Wed May 16, 2012

The interpretation of the measured elliptic and higher order collective flows in heavy-ion collisions in terms of viscous hydrodynamics depends sensitively on the ratio of shear viscosity to entropy density. Here we perform a quantitative comparison between the results of shear viscosities from the ... [Phys. Rev. C 85, 054908 (2012)] Published Mon May 14, 2012

The single-freeze-out model with parametrized hypersurface and flow geometry is employed to analyze the transverse-momentum spectra of hadrons produced in the Pb+Pb collisions at the collision energy of √sNN=2.76 TeV at the CERN Large Hadron Collider (LHC). With the notable exception for protons and... [Phys. Rev. C 85, 054907 (2012)] Published Thu May 10, 2012

We analyze the forward-backward multiplicity correlation coefficient as measured by STAR. We show that in the most central Au + Au collisions bins located symmetrically around η=0 with large separation in pseudorapidity are more strongly correlated than bins located asymmetrically with smaller separ...

Cross-section measurements have been made at 16 and 19 MeV in two exit-channel configurations of neutron-deuteron breakup: the space star and coplanar star.

High spin states of 109In were investigated using the reaction 96Zr(19F, 6n)109In at a beam energy of 105 MeV. New level sequences have been found in this nucleus.

We report on the observation of α decay from a state in 10B at 11.48 MeV. The only observed decay branch is to the first T=1 state in 6Li at 3.56 MeV. The apparent absence of an α-decay branch to the (T=0) ground state in 6Li suggests that the 11.48-MeV state should be assigned isospin T=1. The spin... [Phys. Rev.
