Gamow-Teller transitions in some intermediate-mass nuclei

Abstract

We present the results of an experimental study of allowed Gamow-Teller ${\ensuremath{\beta}}^{+}$ and electron-capture decays of $^{14}\mathrm{O}$, $^{21}\mathrm{Na}$, $^{25}\mathrm{Al}$, $^{26}\mathrm{Si}$, $^{29}\mathrm{P}$, $^{30}\mathrm{P}$, $^{30}\mathrm{S}$, $^{31}\mathrm{S}$, $^{33}\mathrm{Cl}$, $^{34}\mathrm{Cl}$, $^{35}\mathrm{Ar}$, $^{38}\mathrm{Ca}$, and $^{41}\mathrm{Sc}$. Thirteen new branches have been found and the precision has been increased, or upper limits reduced, on the intensities of more than 50 others.RADIO ACTIVITY $^{14}\mathrm{O}$, $^{21}\mathrm{Na}$, $^{25}\mathrm{Al}$, $^{26}\mathrm{Si}$, $^{29}\mathrm{P}$, $^{30}\mathrm{P}$, $^{30}\mathrm{S}$, $^{31}\mathrm{S}$, $^{33}\mathrm{Cl}$, $^{34}\mathrm{Cl}^{m}$, $^{35}\mathrm{Ar}$, $^{38}\mathrm{Ca}$, $^{41}\mathrm{Sc}$ measured ${I}_{\ensuremath{\gamma}}$; $^{26}\mathrm{Si}$, $^{29}\mathrm{P}$, $^{30}\mathrm{S}$, $^{31}\mathrm{S}$, $^{34}\mathrm{Cl}^{m}$, $^{38}\mathrm{Ca}$ measured ${T}_{\frac{1}{2}}$.
