β-decay feeding intensity distribution of ⁶⁴Mn

RADIOACTIVITY ⁶⁴Mn[from ⁹Be(⁸²Se, X), E=140 MeV/nucleon](β^-); measured Eγ, Iγ, γ-sum, βγ-coin; deduced T_1/2, Iβ(E) feedings, B(GT). Comparison to shell-model calculations using using NuShellX@MSU code with GXPF1A and CA48MH1 interaction Hamiltonians. Total absorption summing NaI(Tl) detector (SuN) surrounding the DSSD used for implantation after A1900 fragment separator (NSCL, MSU).

NUCLEAR STRUCTURE ⁶⁴Mn, ⁶⁴Fe; calculated levels, J, π.
