Alpha decay half-lives of superheavy nuclei in the WKB approximation

abstract alpha decay half-lives of superheavy nuclei are obtained in the context of barrier penetration theory built with the use of coulomb and proximity potentials, taking into account the quadrupole deformations of nuclei. it is estimated from a classical viewpoint, a possible maximum value of the angular momentum of alpha particles emitted from odd and odd-odd nuclei. masses and deformations of nuclei are obtained from the macro-microscopic method, with the use of the twocenter shell model. alpha-decay half-lives are compared with recent experimental results
