Improved double-folding alpha-nucleus potential by including nuclear medium effects
Source PublicationPHYSICAL REVIEW C
Language英语
AbstractThe nuclear medium effect in alpha decay is introduced into the microscopic double-folding model to construct an improved alpha-nucleus potential. Under the local density approximation, the alpha-cluster density distribution is considered to vary with the surrounding matter density as a result of the medium effect. The density-dependence of the alpha cluster is incorporated by the width parameter of the Gaussian function and constrained by the critical features derived from previous microscopic studies. The influence of the medium effect to the geometry of the alpha-nucleus potential is studied by comparing with the conventional double-folding potential. To examine the improved potential, the alpha-decay half-lives and preformation factors of even-even spherical nuclei are calculated and compared with experimental data. With the alpha-decay data being well explained, it is concluded that the inclusion of the nuclear medium effect contributes to an improved double-folding alpha-nucleus potential, which incorporates more details of the alpha-decay process.
