EFFECT OF NUCLEAR DEFORMATION ON THE ALPHA-DECAY HALF-LIFE OF EVEN-EVEN ALPHA EMITTERS
Abstract
Alpha-decay half-life of even-even emitters has been calculated in terms of tunnelling through a quantum mechanical potential barrier. A multipolar expansion of Coulomb potential has been developed taking into account the nuclear quadrupole, hexadecapole, and hexacontatetrapole deformations. We show that using a free-parameter model the calculated half-lives do not vary significantly with higher order multipolarities of the daughter nucleus deformation.
