Das Neutroneneinfangspektrum von Sm150

The internal conversion electrons and the gamma-rays emitted by Samarium after neutron capture were measured by means of a betaspectrometer and a bent-crystal spectrometer at the research reactor at Garching near Munich. Lines corresponding to 50 transitions between 59 keV and 1·7 MeV were found with the betaspectrometer. The measurement with the crystal spectrometer showed 11 lines between 250 keV and 740 keV. The multipolarity of a few lines was determined. A level scheme containing most of the measured lines is suggested.
