Nuclear Structure and Decay Data for A=76 Isobars

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 gamma rays. With the exception of structure data for Ga-76 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 Fe-76, Cu-76 and Y-76. Decay scheme characteristics for the decay of Co-76, Ni-76, and Y-76 are unknown while those for decays of Cu-76 and Sr-76 seem incomplete. For Ni-76, very little structure data are available, and for Ga-76 and As-76, 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.
