Contribution
It offers a comprehensive decay scheme of 32Ar and validates shell-model calculations against experimental results.
Findings
All relevant decay branches of 32Ar were identified.
The Gamow-Teller strength distribution matches shell-model predictions.
The Fermi strength aligns with theoretical expectations.
Abstract
In an experiment performed at the SPIRAL1 facility of GANIL, the beta decay of 32Ar 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 32Ar is established.
