摘要: The structure of even-even neutron-rich Ru, Mo, Zr, and Sr nuclei in the A ≈ 100 mass region is studied within interacting boson model (IBM) with microscopic input from self-consistent mean-field approximation based on Gogny-D1M energy density functional. deformation-energy surface quadrupole deformation space (β,γ ), computed constrained Hartree–Fock–Bogoliubov framework, mapped onto expectation value appropriately chosen IBM Hamiltonian configuration mixing condensate state. used to study spectroscopic properties 98–114Ru, 96–112Mo, 94–110Zr, 92–108Sr. Several cases γ -soft behavior are predicted Ru Mo while a pronounced coexistence between strongly prolate weakly oblate deformed shapes found for Zr nuclei. method describes well evolution experimental yrast nonyrast states as selected B(E2) transition probabilities.
