Gamma spectroscopy of $^{150}$Sm

ORAL

Abstract

Nuclei around N=90 are considered transitional nuclei, since they lie in a region between lighter nuclei which display vibrational-like spectra and heavier isotopes with a rotational-like structure.The structure of these transitional nuclei, and in particular the nature of low-lying excited states, still poses a challenge with many competing theoretical model used with varying degrees of success. Differentiating between the models requires more experimental data especially for non yrast collective structures.As part of a program studying nuclei near N=90, the N=88 nucleus $^{150}$Sm has been produced with a $^{149}$Nd($\alpha $,2n)$^{150}$Sm reaction at the Accelerator Laboratory of Jyv\"{a}skyl\"{a}, Finland, employing a 25 MeV $\alpha $-particle beam.Preliminary results focusing on the observed band structures will be presented.
