Nuclear Structure and Decay Data for A=63 Isobars

Experimental nuclear structure and decay data are evaluated for 13 known nuclides of mass number A=63 (Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, Ge, As, Se). Detailed evaluated level properties and related information are presented and recommended spectroscopic parameters are provided, combining all the data from various reactions and decays. No excited state has been observed for ⁶³Ti, ⁶³As and ⁶³Se, among which the first two nuclides have no halflife, decay modes and spin-parity being measured and reported yet. The ground-state spins and/or parities of ⁶³V, ⁶³Cr, ⁶³Mn, and ⁶³Ge still have not been definitely determined and information for excited states in these nuclides plus ⁶³Fe is limited. Information for ⁶³Ga is mostly from one measurement and no data for ⁶³Ge ε+β⁺ decay have been measured while this decay mode (%100) of the ⁶³Ge parent is known. The ⁶³Cu nuclide is the most extensively studied via more than 28 different reactions and decays, followed by ⁶³Zn and ⁶³Ni. Among all those nuclides, only ⁶³Cu has a complete radioactive decay scheme. This work supersedes earlier full evaluations of A=63 published by 2001Ba27, 1991Ki10, 1979Au10, and 1975Au03.
