Abstract
Dynamic deformation theory based on Kumar and Baranger's pairing-plus-quadrupole model (1968) is employed to calculate the collective states of 150Sm. A delicate balance of the pairing and quadrupole forces, leading to an interchange of the K-identification of the second and the third 2+ states at a critical value, is exhibited. An improved solution of the collective Hamiltonian, compared Kumar's calculation (1974), removes most of the discrepancies between the calculated and experimental branching ratios. Comparison with the experimental X(EO/E2) values is also given.Keywords
