Half-life and branching ratios for the β decay of 38Ca

. In an experiment at the LISE3 facility of GANIL, we have studied with high precision the decay of 38 Ca. The LISE3 facility allowed to produce close to pure samples of the nuclide of interest. We measured the half-life of this nucleus to be 443.63(35)ms, whereas the super-allowed branching ratio w...

Zusammenfassung:	. In an experiment at the LISE3 facility of GANIL, we have studied with high precision the decay of 38 Ca. The LISE3 facility allowed to produce close to pure samples of the nuclide of interest. We measured the half-life of this nucleus to be 443.63(35)ms, whereas the super-allowed branching ratio was determined to be 77.14(35)%. Both data are in nice agreement with previous high-precision measurements and thus improve the overall precision of the experimental inputs to determine the corrected value for this nucleus. We also compare the experimental Gamow-Teller strength distribution with theoretical shell-model predictions. Finally, future opportunities at LISE3 are discussed.
