Phys. Rev. C 79, 054320 (2009) [7 pages]Low-energy structure of 61Mn populated following β decay of 61CrReceived 16 March 2009; published 15 May 2009 β decay of the 61Cr37 ground state has been studied. A new half-life of 233±11 ms has been deduced, and seven delayed γ rays have been assigned to the daughter 61Mn36. The low-energy level structure of 61Mn36 is similar to that of the less neutron-rich 57,59Mn nuclei. The odd-A25Mn isotopes follow the systematic trend in the yrast states of the even-even, Z+1 26Fe isotopes, and not that of the Z-1 24Cr isotopes, where a possible onset of collectivity has been suggested to occur already at N=36. © 2009 The American Physical Society URL:
