Investigation of A ∼100 mass region up to exotic with interacting boson model

Even‐even nuclei in the A ∼100 mass region are investigated within the framework of the interacting boson model‐1 (IBM‐1). The parametrization established on the basis of known elements is then used to predict properties of the unknown. This paper includes the predicted energy spectra and the potential energy surface obtained from the IBM‐1 hamiltonian in the classical limit.
