[en] Nuclear spectroscopic information for known nuclides of mass number 73 (Co,Ni,Cu,Zn,Ga,Ge,As,Se,Br,Kr, Rb,Sr)has been evaluated and presented together with adopted energies and J d of levels in these nuclei.No data are yet available for excited states in ⁷³Co, ⁷³Ni and ⁷³Sr. The existence and decay of a 5.8-s isomer in ⁷³Zn remain uncertain.The isomeric decay of 107-ns isomer in ⁷³Kr suffers from poor intensity balance at the first excited state.This evaluation supersedes earlier complete evaluations published by [Nucl.Data Sheets 69 (1993) 857], [Nucl.Data Sheets 29 (1980) 1] and [Nucl.Data Sheets 13 (1974) 305]; and an update by [Nucl.Data Sheets 51 (1987) 161]
