$\beta^+$ and electron capture of fp shell nuclei with $Tz=-2$

Nuclear Theory 2009-10-30 v1

Abstract

Allowed β+\beta^+ branches of very proton-rich fpfp shell Tz=2Tz=-2 nuclei at the proton drip-line are calculated in the full fp valence space. The β+\beta^+ decay half-lives calculated with the standard quenching factor (gAeff/gAg^{eff}_{A}/g_{A})=0.74 are in good agreement with existing experimental data. Detailed branching Gamow-Teller strength are predicted but comparison with experiment is still difficult since, in most cases, spectroscopic information is not yet available.
