Various aspects of the Deformation Dependent Mass model of nuclear structure
D. Petrellis, Dennis Bonatsos, N. Minkov
Recently, a variant of the Bohr Hamiltonian was proposed where the mass term is allowed to depend on the beta variable of nuclear deformation. Analytic solutions of this modified H…
Proton-Neutron Pairs in Heavy Deformed Nuclei
Dennis Bonatsos, I. E. Assimakis, Andriana Martinou
The microscopic justification of the emergence of SU(3) symmetry in heavy nuclei remains an interesting problem. In the past, the pseudo-SU(3) approach has been used, with consider…
Bohr Hamiltonian with a deformation-dependent mass term: physical meaning of the free parameter
Dennis Bonatsos, N. Minkov, D. Petrellis
Embedding of the 5-dimensional (5D) space of the Bohr Hamiltonian with a deformation-dependent mass (DDM) into a 6-dimensional (6D) space shows that the free parameter in the depen…
Analytical solutions for the Bohr Hamiltonian with the Woods-Saxon potential
M. Capak, D. Petrellis, B. Gonul +1
Approximate analytical solutions in closed form are obtained for the 5-dimensional Bohr Hamiltonian with the Woods-Saxon potential, taking advantage of the Pekeris approximation an…
Regularity and chaos in 0+ states of the interacting boson model using quantum measures
S. Karampagia, Dennis Bonatsos, R. F. Casten
Statistical measures of chaos have long been used in the study of chaotic dynamics in the framework of the interacting boson model. The use of large number of bosons renders additi…
Octupole deformation in light actinides within an analytic quadrupole octupole axially symmetric model with Davidson potential
Dennis Bonatsos, Andriana Martinou, N. Minkov +2
The analytic quadrupole octupole axially symmetric model, which had successfully predicted 226Ra and 226Th as lying at the border between the regions of octupole deformation and oc…
