摘要：

The alpha-decay half lives of superheavy elements have been calculated in the frame-work of WKB method. The effective potential has been considered as summation of the deformed Woods-Saxon nuclear potential, deformed Coulomb potential and centrifugal term. The quadrupole, hexadecapole and hexacontatetrapole deformations have been included in the calculation. The effect of hexacontatetrapole deformation on the potential barrier has been presented, separately. The good agreement between theory and experiment has been observed for alpha-decay half-lives of heavy and superheavy elements.
