Abstract EN
We present results for β -decay half-lives based on a new recipe for calculation of phase space factors recently introduced.
Our study includes f p -shell and heavier nuclei of experimental and astrophysical interests.
The investigation of the kinematics of some β -decay half-lives is presented, and new phase space factor values are compared with those obtained with previous theoretical approximations.
Accurate calculation of nuclear matrix elements is a prerequisite for reliable computation of β -decay half-lives and is not the subject of this paper.
This paper explores if improvements in calculating the β -decay half-lives can be obtained when using a given set of nuclear matrix elements and employing the new values of the phase space factors.
Although the largest uncertainty in half-lives computations come from the nuclear matrix elements, introduction of the new values of the phase space factors may improve the comparison with experiment.
The new half-lives are systematically larger than previous calculations and may have interesting consequences for calculation of stellar rates.
