Abstract :In this study, we employed the interacting boson model insert ignore into journalissuearticles values(IBM-1); to determine the most appropriate Hamiltonian for the study of 94-108Mo, 94-110Ru, and 96-114Pd isotopes in the region A cong 100. The soft rotor formula insert ignore into journalissuearticles values(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 Binsert ignore into journalissuearticles values(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 gamma-band energy staggering in low-spin, back bending effect, low energy spectra of even-even Mo, Ru, and Pd nuclei is also discussed.
