Abstract :
The Search for new super heavy elements is at present one of the most exciting adventures in the field of nuclear physics. Majority of super heavy elements are identified through alpha decay chain since many nuclei in the super heavy region are expected to decay mainly by alpha emission. Alpha decay is a unique tool to study the properties of a nucleus which assists for the experimental studies of super heavy nuclei, as it makes their identification easier. In order to investigate such alpha decay half-life times of super heavy nuclei, Cubic plus Yukawa plus Exponential (CYE) model in the Trans-Actinide region ranging from Z = 104 to 121. This model uses a cubic potential in the over-lapping region connected by a Yukawa plus Exponential potential in the post – scission region. Apart from using this potential CYE model has more virtues, for instance inclusion of zero point vibration energy. Such a model is enhanced further by incorporating the consequence of deformation of the decay parent and the daughter nucleus. This can cause longevity and stability of super heavy nuclei. The expected long lived super heavy nuclei provide the physicists to have an extensive study about the properties of super heavy elements. In this work by using CYE model the alpha decay half-lives of Super heavy nucleus including the effect of nuclear deformation is analyzed.
