In this paper, nuclear structure of yrast state bands of even-even 120-130Te isotopes has been studied under the frame work of interacting boson model (IBM-1). The theoretical energy levels for Z=52, even N = 68-78 up to 12+ state have been obtained by using the MatLab 6.5 computer program. The ratio of the excitation energies of first 4+ and first 2+ excited states, R4/2, has been also calculated for those nuclei. The values of the parameters in the IBM-1 hamiltonian yield the best fit to the experimental energy spectrum. The results are compared with the most recent experimental values where an acceptable degree of agreement is achieved. Moreover, as a measure to quantify the evolution, we have studied the transition rate R of some of the low-lying quadrupole collective states in comparison to the available experimental data. In this paper, the properties of even 120-130Te isotopes have been considered to the U(5) transitional region of IBM-1.
