Das Konversionselektronenspektrum von Sm150 nach Neutroneneinfang

The spectrum of internal conversion electrons emitted by Sm¹⁵⁰ after neutron capture was measured by means of the beta spectrometer at the research reactor at Garching near Munich. Between 3 keV and 8 MeV, 392 conversion lines corresponding to 337 transitions were found. The multipolarity of most transitions could be determined uniquely, the energy of the conversion electrons was measured within an accuracy of≧2.5 × 10^?4. An extension of the level scheme of Sm¹⁵⁰ is proposed.
