In this paper, the yrast states and the electric reduced transition probabilities B(E2) ↓ from gamma transition 8⁺ to 6⁺, 6⁺ to 4⁺, 4⁺ to 2⁺ and 2⁺ to 0⁺ states of neutron rich ¹²²Te nucleus in the frame work of Interacting Boson Model-I (IBM-I) have carried out. The calculated results have been compared with the available experimental values. The ratio of the excitation energies of first 4⁺ and 2⁺ excited states (R₄/₂), have also been calculated for this nucleus. An acceptable degree of agreement between the predictions of IBM-I model and experiment is achieved. Moreover, as a measure to quantify evolution, we studied the transition rate R = B(E2 : L⁺ → (L - 2)⁺ ) / B(E2 : 2⁺ → 0⁺ ) of some of the low-lying quadrupole collective states in comparison to the available experimental data. The IBM-I formula for energy levels and the reduced transition probabilities B(E2) have been analytically deduced in the U(5) limit for a few yrast states transitions in ¹²²Te isotope.
