Abstract

Targets of 148Sm, 150Sm, 152Sm and 154Sm have been bombarded with 12.1 MeV deuterons and the spectra of inelastic deuterons observed at 60°, 90°, 125° and 155° by means of a high resolution magnetic spectrograph.

For the strongly populated levels the multipolarities of the excitations were determined from the slopes of the angular distributions which are characteristic functions of the multipolarity. The cross sections from the 2+ and 3 states were compared to the corresponding reduced transition probabilities B(Eλ) determined by Coulomb excitation with 15 or 16 MeV α-particles. On this basis, a normalization was obtained which allowed the extraction of reduced transition probabilities from the yields of inelastically scattered deuterons.

The results are compared to previous studies and the nature of some of the states observed is discussed.
