Effect of multipolarity deformation and spin in odd-a nucleus - ¹¹⁷Ts

Now a days, the study of superheavy nuclei (SHN) i.e, Z≥100 becomes the most interesting topics for both theorists and experimentalists. In the nuclear chart, these nuclei are located at the extremes of nuclear landscape. The key procedure for synthesizing SHN is the fusion of heavy nuclei just over the fission barrier. The aim of our work is to calculate the decay properties of odd-A Superheavy nuclei of Z=117 using our Cubic plus Yukawa plus Exponential model (CYEM) for spherical and spheroid nucleus with deformation effects (β₂, β₄ and β₆) and also centrifugal potential (l). Here our calculated half life time values are compared with the improved Royer's analytical values
