Phys. Rev. C 71, 054306 (2005) [7 pages]Simple description of light W, Os, and Pt nuclei in the interacting boson modelReceived 11 January 2005; published 19 May 2005 A simple, two-parameter IBA-1 Hamiltonian is applied to light W, Os, and Pt nuclei with N ≤ 104. Equal emphasis is placed on fitting all low-lying positive parity excitations resulting in a good description of energy levels and electromagnetic transition rates. A mapping of these parameters into the IBA symmetry triangle finds that these nuclei lie rather central in the triangle and close to the phase transition region of the IBA model. © 2005 The American Physical Society URL:
