Özet
Even-even nuclei in the A similar to 100 mass region are investigated within the framework of the interacting boson model-1 (IBM-1). The study includes energy spectra and electric quadrupole transition properties of zirconium, molybdenum, ruthenium and palladium isotopes with neutron number N >= 54. A global parametrization of the IBM-1 hamiltonian is found leading to a description of 301 collective levels in 30 nuclei with a root-mean-square deviation from the observed level energies of 119 keV The geometric character of the nuclei can be visualized by plotting the potential energy surface V(beta, gamma) obtained from the IBM-1 hamiltonian in the classical limit. The parametrization established on the basis of known elements is then used to predict properties of the unknown. neutron-rich isotopes Zr-106, (MO)-M-112, Ru-116 and Pd-120.
