The study includes energy spectra and electric quadrupole transition properties of zirconium, molybdenum, ruthenium and palladium isotopes with neutron number N >= 52. A global parametrization of the IBM-1 Hamiltonian is found leading to a description of about 300 collective levels in 30 nuclei with a root-mean-square deviation from the observed level energies of 120 keV. The importance of the d(5/2) subshell closure at neutron number N = 56 is pointed out. 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 used to predict properties of the unknown, neutron-rich isotopes (106)Zr, (112)Mo, (116)Ru and (122)Pd.eninfo:eu-repo/semantics/closedAccessArticle371010.1088/0954-3899/37/10/1051022-s2.0-78149422219Q1WOS:000282276700020Q2
