The decay of the nuclides 75Se and 75Ge

Gamma transitions in the decay of the nuclides 75Se and 75Ge have been investigated by scintillation spectroscopy. Single spectra and coincidence spectra were found to conform with the level schemes constructed by previous authors. Directional correlations of five γ cascades have been measured. Polarization correlation measurements were performed on the 121 keV — 280 keV and 136 keV — 265 keV γ cascades. The following spins and parities have been assigned to levels in 75As: ground state 3/2−, 199 keV ½−, 265 keV 3/2−, 280 keV 5/2t-, 304 keV 9/2+, 401 keV 5/2+
