Abstract

The high spin states of the nucleus 150Sm were populated via the 4n channel following a fusion evaporation reaction 136Xe(18O, 4n)150Sm. The de-excitation gamma-rays were detected using the AFRODITE spectrometer array at iThemba LABS. Life time measurements were performed using the Doppler shift attenuation method technique (DSAM) [1]. Experimental transition strengths (BE2) obtained using the life times are presented together with the measured angular intensity ratios and linear polarization anisotropy. A new decay scheme of 150Sm with the rearrangements of some mystery decay paths seen from Urban et al. [1] is also presented. [1] T. K. Alexander, J. S. Foster, M. Baranger, and E. Vogt.
