Nuclear Structure and Decay Data for A=65 Isobars

Abstract

Experimental nuclear structure and decay data are evaluated for 13 known nuclides of mass number A=65 (V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga Ge, As, Se, Br). Detailed evaluated level properties and related information are presented and recommended spectroscopic parameters are provided, combining all the data from various reactions and decays. At the proton-rich end, ⁶⁵Br has been studied theoretically but still remains unobserved experimentally, while at the neutron-rich end, ⁶⁵V has been observed, but its ground-state T_1/2 and J^π wait to be measured and determined. No excited state has been observed for ⁶⁵V, ⁶⁵Cr, and ⁶⁵Se. The ground-state spins and/or parities of ⁶⁵Fe, ⁶⁵Co, ⁶⁵Ge, ⁶⁵As, and ⁶⁵Se still have not been definitely determined. Information for excited states in ⁶⁵Mn and ⁶⁵As is very limited. ⁶⁵Cu is the most extensively studied via 26 different reactions and decays, followed by ⁶⁵Zn and ⁶⁵Ga. For ⁶⁵Co and ⁶⁵Ni, their radioactive decay schemes are incomplete. This work supersedes earlier full evaluations of A=65 published by 2010Br10, 1993Bh04, 1986Wa02, and 1975Au08.
