Nuclear data sheets update for A = 64

Abstract

The evaluated spectroscopic data are presented for eight known nuclides of mass 64 (Mn, Fe, Co, Ni, Cu, Zn, Ga, Ge). Excited-state data are nonexistent for 64Mn and 64Fe. Very little information is available for 64Ge and γ-ray data are scarce for 64Co and 64Ni. Some high-spin data are available for 64Ga and 64Ge, in spite of several in-beam γ-ray experiments on 64Zn and 64Cu. Further work on 64Zn and 64Ga seems to be in progress at Daresbury (90LiZS) through heavy-ion reactions. Radioactive decay data for 64Mn are not available and those for 64Fe, 64Co and 64Ge are not considered definitive.
