The ground state rotational bands in 150Sm and 152Sm
The gamma rays from the 150Nd ( alpha ,4n) 150Sm and 150Nd ( alpha ,2n) 152Sm reactions have been studied both in singles and coincidence. The ground state rotational bands in 150Sm and 152Sm are populated up to the state with spin 10+. It is found that the nuclear moment of inertia of 150Sm is substantially lower than that of 152Sm for the low spin states, but that it increases with spin and the moments of inertia converge for the high spin states. This supports earlier evidence that the change from spherical to deformed nuclei between N=88 and N=90 is gradual.
