Nuclear Structure and Decay Data for A=76 Isobars

Abstract

The experimental nuclear spectroscopic data for known nuclides of mass number 76 (Fe, Co, Ni, Cu, Zn, Ga, Ge, As, Se, Br, Kr, Rb, Sr, Y) have been evaluated and presented together with Adopted properties for levels and γ rays. With the exception of structure data for 76Ga nucleus, significant new data have been incorporated for all the other nuclides of A=76 since the previous 1995 update in ENSDF database and NDS publication 1995Si03. No data are yet available for excited states in 76Fe, 76Cu and 76Y. Decay scheme characteristics for the decay of 76Co, 76Ni, and 76Y are unknown while those for decays of 76Cu and 76Sr seem incomplete. For 76Ni, very little structure data are available, and for 76Ga and 76As, only low-spin (J<4 or so) information is available. This work supersedes the data presented in the previous (1995Si03) NDS evaluation of A=76.
