Nuclear Data Sheets for A=85

Evaluated experimental data are presented for 13 known nuclides of mass 85 (Zn, Ga, Ge, As, Se, Br, Kr, Rb, Sr, Y, Zr, Nb, Mo). Since the previous 1990 evaluation of A=85, 85Zn, 85Ga, 85Ge and 85nuclides are newly added here. Excited state data for 85Se, 85Zr have become available from radioactive decay and in–beam γ–ray studies. New and improved high–spin data are available for 85Br, 85Kr, 85Rb, 85Y, 85Nb and 85Mo. New direct and precise measurement of atomic masses of 85Ge, 85As, 85Se, 85Br, 85Rb, 85Zr, 85Nb and 85Mo have greatly improved the landscape of β decay–Q values and separation energies in this mass region.In spite of extensive experimental work on the isobaric nuclei of this mass chain several deficiencies remain. No excited states are known in 85Zn, 85Ga, 85As. Only a few excited state are assigned in 85Ge from 85Ga β– decay. From radioactivity studies, the decay schemes of 85Zn and 85Mo are not known, and those for 85Ga, 85Ge, 85As and 10.9–s isomer of 85Zr are incomplete. Level lifetimes are not known for excited states in 85Se, 85Br, 85Nb and 85Mo. The 85Tc nuclide has not been detected in fragmentation experiments at GANIL, alluding to its unbound nature for proton emission. The 85Kr, 85Rb, 85Sr, and 85Y nuclides remain the most extensively studied from many different reactions and decays.The evaluation of A=85 nuclides has been done after a span of 23 years, thus includes an extensive amount of new data for almost each nuclide. This work supersedes the data for A=85 nuclides presented in earlier full NDS publication by J. Tepel in 1980Te04 and a later one published in an update mode by H. Sievers in 1991Si01
