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 - stated at a are nonexistent for Ni-78, Cu-78 and Zr-78. For Zr-78, only the isotopic identification is established without any knowledge of its half - life and decay modes. Only limited excited state data exist for Y-78. The radioactive decays of the following isotopes are not considered by the evaluators as well established: Cu-78, (78)mRb, Sr-78 and Y-78. High - spin excitations are known for As-78, Se-78, Br-78, Kr-78, Rb-78 and 78Sr. Significant amounts of new data have been added since the last NDS publication of A=78 evaluation more than 18 years ago.
