Implementation of the Moments Method in TALYS: Sensitivity of Fe observables to shell model nuclear level densities
Lucas Chouinard, Sofia Karampagia
The Moments Method (MM), a statistical spectroscopy framework built upon configuration interaction shell model Hamiltonians that enables shell model descriptions of nuclear level d…
Enhanced low-energy -decay strength of Ni and its robustness within the shell model
A. C. Larsen, J. E. Midtbø, M. Guttormsen +19
Neutron-capture reactions on very neutron-rich nuclei are essential for heavy-element nucleosynthesis through the rapid neutron-capture process, now shown to take place in neutron-…
Level density of the -nuclei statistical shell-model predictions
S. Karampagia, R. A. Senkov, V. Zelevinsky
Accurate knowledge of the nuclear level density is important both from a theoretical viewpoint as a powerful instrument for studying nuclear structure and for numerous applications…
Quantum phase transitions and collective enhancement of level density in odd-A and odd-odd nuclei
S. Karampagia, A. Renzaglia, V. Zelevinsky
The nuclear shell model assumes an effective mean-field plus interaction Hamiltonian in a specific configuration space. We want to understand how various interaction matrix element…
Low energy magnetic radiation enhancement in the f shell
S. Karampagia, B. A. Brown, V. Zelevinsky
Studies of the -ray strength functions can reveal useful information concerning underlying nuclear structure. Accumulated experimental data on the strength functions show an enh…
Nuclear shape transitions, level density, and underlying interactions
S. Karampagia, Vladimir Zelevinsky
The configuration interaction approach to nuclear structure uses the effective Hamiltonian in a finite orbital space. The various parts of this Hamiltonian and their interplay are…
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…
Analytic derivation of an approximate SU(3) symmetry inside the symmetry triangle of the Interacting Boson Approximation model
Dennis Bonatsos, S. Karampagia, R. F. Casten
Using the contraction of the SU(3) algebra to the algebra of the rigid rotator in the large boson number limit of the Interacting Boson Approximation (IBA) model, a line is found i…
