Bohr-Mottelson Hamiltonian with octic potential applied to the Cd isotopes
P. Buganu, R. Budaca
The Bohr-Mottelson Hamiltonian, with an octic potential in the -deformation variable, is numerically solved for a -unstable symmetry of the nuclear system. The analytical str…

A. Ait Ben Mennana, R. Benjedi, P. Buganu +5
The deformation properties of 74Ge, 74Se and 74Kr are studied within the phenomenological Bohr-Mottelson model, having as input the experimental collective energy states, as well w…
A -rigid solution of the Bohr Hamiltonian with deformation-dependent mass term for Kratzer potential and
S. Ait El Korchi, S. Baid, P. Buganu +4
In this work, the Davydov-Chaban Hamiltonian, describing the collective motion of -rigid atomic nuclei, is amended by allowing the mass parameter to depend on the nuclear deform…
