High-spin level structure and Ground-state phase transition in the odd-mass 103-109 Rh isotopes in the framework of exactly solvable sdg interacting boson-fermion model

摘要: Abstract In this article, the negative-parity states in odd-mass Rh 103 − 109 isotopes terms of sd and sdg interacting-boson fermion models were studied. The transitional interacting boson–fermion model Hamiltonians sdg-IBFM versions based on affine S U ( 1 , ) Lie Algebra employed to describe evolution from spherical deformed gamma unstable shapes along with chain isotopes. method, Hamiltonian, which is a three level pairing Hamiltonian was determined easily via exactly solvable method. Some observables shape phase transitions such as energy levels, two neutron separation energies, signature splitting γ-vibrational band, α-decay double β -decay energies calculated examined for these present calculation correctly reproduces gamma-soft transition comparisons made sd-IBFM.
