Spectroscopic study of β-delayed particle emission from proton-rich nucleus 23Si

The β-delayed particle emission from the exotic nucleus 23Si has been studied using a detection system with silicon array and clover-type high-purity germanium (HPGe) detectors. The β-delayed charged-particle spectrum and γ-ray spectrum were identified. The half-life of 23Si has been determined. A new β-delayed proton branch with an energy of 3811keV was observed. The β-delayed two-proton emission was confirmed.
