Complementary descriptions of shape/phase transitions in atomic nuclei
Dennis Bonatsos, E. A. McCutchan, N. V. Zamfir
Shape/phase transitions in atomic nuclei have first been discovered in the framework of the Interacting Boson Approximation (IBA) model. Critical point symmetries appropriate for n…
Unified description of 0+ states in a large class of nuclear collective models
Dennis Bonatsos, E. A. McCutchan, R. F. Casten
A remarkably simple regularity in the energies of 0+ states in a broad class of collective models is discussed. A single formula for all 0+ states in flat-bottomed infinite potenti…
Simple, empirical order parameter for a first order quantum phase transition in atomic nuclei
Dennis Bonatsos, E. A. McCutchan, R. F. Casten +1
A simple, empirical signature of a first order phase transition in atomic nuclei is presented, the ratio of the energy of the 6+ level of the ground state band to the energy of the…
Heavy deformed nuclei in the shell model Monte Carlo method
Y. Alhassid, L. Fang, H. Nakada
We extend the shell model Monte Carlo approach to heavy deformed nuclei using a new proton-neutron formalism. The low excitation energies of such nuclei necessitate calculations at…
Effective shell model Hamiltonians from density functional theory: quadrupolar and pairing correlations
R. Rodriguez-Guzman, Y. Alhassid, G. F. Bertsch
We describe a procedure for mapping a self-consistent mean-field theory (also known as density functional theory) into a shell model Hamiltonian that includes quadrupole-quadrupole…
Large-scale prediction of the parity distribution in the nuclear level density and application to astrophysical reaction rates
D. Mocelj, T. Rauscher, G. Martinez-Pinedo +5
A generalized method to calculate the excitation-energy dependent parity ratio in the nuclear level density is presented, using the assumption of Poisson distributed independent qu…
