Moment of Inertia ofDy158from Excitation of the Ground-State Band to Spin 22

Abstract
The behavior of the moment of inertia for high-spin states in Dy158 has been studied by populating the ground-state band up to spin 22 through the reaction Nd150(C13, 5N)Dy158 at bombarding energies of up to 72 MeV. The rate of increase of the moment of inertia I with rotational frequency rises abruptly in the region from spin 14 to 18. In the region of spin 22, I tends toward a more constant value.
