Evidence of triaxiality in ¹⁶²Er

In the present work, we use soft rotor formula for evaluating the γ - band energies which has recently been modified. We will show that the energies obtained by the formula by using three input parameters only, are very close to the experimental data. This work not only hints at the rotational character of the nucleus but, assign nearly rigid shape to the nucleus. Our view point is further supported by the recently published data on some interband transition within γ - band and also from γ - band to yrast band
