In an experiment at the LISE3 facility of GANIL, we have studied with high precision the0+ → 0+ $\beta$ decay of 38Ca. The LISE3 facility allowed to produce close to pure samples of the nuclide ofinterest.We measured the half-life of this nucleus to be 443.63(35)ms, whereas the super-allowed branchingratio was determined to be 77.14(35)%. Both data are in nice agreement with previous high-precisionmeasurements and thus improve the overall precision of the experimental inputs to determine the correctedFt value for this nucleus. We also compare the experimental Gamow-Teller strength distribution withtheoretical shell-model predictions. Finally, future opportunities at LISE3 are discussed.Read less <
