Nuclear Data Sheets for A = 71

The evaluated spectroscopic data are presented for experimentally known nuclides of mass 71 (Mn,Fe,Co,Ni,Cu,Zn,Ga,Ge,As,Se,Br,Kr). Excited-state data are nonexistent for ⁷¹Mn, ⁷¹Fe, ⁷¹Co and ⁷¹Kr. Significant new data have been added since the last evaluation of A=71 nuclides by M. Bhat (1993Bh02). Excited states are now known in ⁷¹Ni and ⁷¹Cu, and enhanced information about high-spin excitations is available for ⁷¹Ga, ⁷¹As and ⁷¹Br. The decay schemes of radioactive isotopes ⁷¹Mn and ⁷¹Fe are not known at all, and those for ⁷¹Co, ^71mNi and ⁷¹Kr are not known well. For the decay of ⁷¹Cu, ^71gNi, and ⁷¹Br, extensive data are available, but in the opinion of the evaluators the decay schemes still seem incomplete.This work supersedes earlier full evaluations of A=71 published by 1988Bh01, 1979Ke06 and 1973Al33, and the last one published in ‘update’ mode by 1993Bh02.
