| Summary: | Alpha decay is one of the earliest known decay modes. The study of alpha decay
has been a useful tool to probe the nuclear structure by providing information about
ground state energy, half-lives, nuclear deformation, etc. Furthermore, a better
prediction of alpha decay half-lives is continously needed for the synthesis of new
elements and isotopes.
The alpha decay process has been explained by Gamow and by Gurney and Condon
as a phenomenon of quantum tunneling where the alpha particle strikes against the
potential barrier with a finite probability of penetration. This probability depends
on the potential barrier which is a sum of the Coulomb potential, the centrifugal
potential, and the nuclear potential. The nuclear potential remains an open problem
to this day. In this work, a Woods-Saxon potential is used for the nuclear potential.
This work aims to calculate the alpha decay half-lives of even-even nuclei of Z=62
to 100 within the Unified Fission Model based on a Woods-Saxon potential. The
calculation is done numerically using a Matlab program. The calculated values are
compared to experimental values and it is found that they follow the same pattern
and are almost the same.
