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.

在GANIL的SPIRAL1设施进行的一项实验中,已经通过与来自EXOGAM阵列的锗三叶草探测器相关联的“硅立方”设备研究了\(^ {32} \) Ar的\(\ beta \)衰变。观测到了β延迟质子和\(\ gamma \)射线,并可以确定所有相关的衰变分支。将Gamow-Teller强度分布与壳模型计算进行了比较,发现了极好的一致性。费米的实力符合预期。建立了\(^ {32} \) Ar的准完全衰减方案。
