The Disintegration ofSe75

The photoelectrons produced in both lead and uranium radiators by the gamma-rays following $K$-capture in ${\mathrm{Se}}^{75}$ have been investigated using a uniform field, semi-circular magnetic spectrometer. The gamma-rays thus found have energies of 76 kev, 123 kev, 137 kev, 267 kev, 283 kev, and 405 kev with a possible radiation at approximately 99 kev. A tentative decay scheme is proposed.
