Structure and odd‒even staggering of Mo, Ru, and Pd even‒even nuclei in the framework of IBM-1

In this study, we employed the interacting boson model (IBM-1) to determine the most appropriateHamiltonian for the study of 94-108 Mo, 94-110 Ru, and 96-114 Pd isotopes in the region Aapproximately equal to100. The soft rotor formula (SRF) calculation was also done to study these isotopes. Using the best fit values of parameters to construct the Hamiltonian of the IBM-1 we calculated energy levels and B(E2) values for number of transitions in Mo, Ru, and Pd nuclei. The results obtained from the IBM-1 and SRF were compared with experimental data and IBM-2 calculation. On comparing the results it was observed that they were in good agreement with each other. The ɤ -band energy staggering in low-spin, back bending effect, low energy spectra of even-even Mo, Ru, and Pd nuclei is also discussed.
