Abstract
Experimental nuclear spectroscopic data are evaluated for 12 known nuclides of mass number=71 (Mn, Fe, Co, Ni, Cu, Zn, Ga, Ge, As, Se, Br, Kr). Detailed compiled and evaluated information is presented for each reaction and decay experiment. The β−n decay of 72Co to 71Ni is included in this work, while for β−n decay of 71Co to 70Ni, consult Nuclear Data Sheets for A=70 (2016Gu11) or the ENSDF database for 70Ni. Combining all the available data, recommended values are provided for energies, spins and parities, and half-lives of levels, with energies, branching ratios and multipolarities of γ radiations, and characteristics of β and α radiations in radioactive decays. Excited-states have not yet been identified in 71Mn, 71Fe, and 71Kr, with the ground-state half-life remaining unknown only for 71Mn; data for excited states in 71Co and 71Ni are very limited; 71Ga, 71Ge and 71As are the most extensively studied nuclides via various reactions and decays, followed by 71Cu, 71Zn, 71Se, and 71Br, however, except for 71Ge, the decay schemes of all other nuclides are considered as incomplete due to a large gap between the decay Q-value and the highest observed level. This work supersedes earlier evaluations of A=71 by 2011Ab01.
期刊介绍:
The Nuclear Data Sheets are current and are published monthly. They are devoted to compilation and evaluations of experimental and theoretical results in Nuclear Physics. The journal is mostly produced from Evaluated Nuclear Structure Data File (ENSDF), a computer file maintained by the US National Nuclear Data Center
