In this study, we employed the interacting boson model (IBM-1) to determine the most appropriate Hamiltonian for the study of 94−108 Mo, 94−110 Ru, and 96−114 Pd isotopes in the region A ∼ = 100 . 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

The γ -band energy staggering in low-spin, back bending effect, low energy spectra of even-even Mo, Ru, and Pd nuclei is also discussed.
