Nuclear data sheets for A=64

The evaluated spectroscopic data are presented for known nuclides of mass 64 (V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga,Ge,As,Se). Excited-state data are nonexistent for V-64, Cr-64, As-64 and Se-64. Except for half-lives, no other radioactive decay data are available for the decay of V-64, As-64 and Se-64; and those for the decays of Cr-64, Mo-64, Fe-64, Co-64 and Ge-64 are not considered as definitive. There are several high-spin studies for Zn-64 nuclide, but many inconsistencies are noted in this evaluation and complete details of data in these studies are generally lacking in the published literature. This work supersedes earlier full evaluations of A=64 by 1996Si12, 1979Ha35, 1974Au04 and 1967Ve09; and a mid-strem evaluation by 1991Si03 published in an 'Update' mode.
