Nuclear Data Sheets for A = 78

The evaluated spectroscopic data are presented for known nuclides of mass 78 (Ni,Cu,Zn,Ga,Ge,As,Se,Br,Kr,Rb,Sr,Y,Zr). Excited-state data are nonexistent for ⁷⁸Ni, ⁷⁸Cu and ⁷⁸Zr. For ⁷⁸Zr, only the isotopic identification is established without any knowledge of its half-life and decay modes. Only limited excited state data exist for ⁷⁸Y. The radioactive decays of the following isotopes are not considered by the evaluators as well established: ⁷⁸Cu, ^78mRb, ⁷⁸Sr and ⁷⁸Y. High-spin excitations are known for ⁷⁸As, ⁷⁸Se, ⁷⁸Br, ⁷⁸Kr, ⁷⁸Rb and ⁷⁸Sr. Significant amounts of new data have been added since the last NDS publication of A = 78 evaluation more than 18 years ago.This work supersedes earlier full evaluations of A = 78 published by 1981Si13 and 1975Ru01 and the one published in ‘update’ mode by 1991Ra06.
