In this article, we considered the dependence of the rate of energy transition on various parameters and how the energy-transition -rate changes as a function of radius R. We observed that with increasing radius R, the energy-flip-rate decreases, which is perfectly consistent with a system approaching ferromagnetic order. Also the energy-transition-rate for different choices of the amplitude of the impurities, for a purely static potential scatter, no energy transition occurs, but for magnetic impurities, we observed a high peak in the energy-transition-rate for one particular amplitude of order 5  . Different profiles of energy-transition-rate (ETR) against frequencies and amplitude are drawn respectively, for angle , θ , with µBB0=0.5 and     x = R2 = 100 and different values of frequencies and amplitude.
