A $\gamma$-rigid solution of the Bohr Hamiltonian with deformation-dependent mass term for Kratzer potential and $\gamma =30^{\circ }$

S. Ait El Korchi, S. Baid, P. Buganu +4

In this work, the Davydov-Chaban Hamiltonian, describing the collective motion of $\gamma$-rigid atomic nuclei, is amended by allowing the mass parameter to depend on the nuclear deform…
