Abstract
In an experiment performed at the SPIRAL1 facility of GANIL, the \(\beta \) decay of \(^{32}\)Ar has been studied by means of the “Silicon Cube” device associated with germanium clover detectors from the EXOGAM array. Beta-delayed protons and \(\gamma \) rays have been observed and allowed the determination of all relevant decay branches. The Gamow–Teller strength distribution is compared to shell-model calculations and excellent agreement is found. The Fermi strength is inline with expectations. A quasi-complete decay scheme of \(^{32}\)Ar is established.
