| contents | This research explores the beta decay of the proton-rich nucleus 23Al. The nucleus was generated at the National Superconducting Cyclotron Laboratory (NSCL) through projectile fragmentation, utilizing a primary beam of 36Ar ions directed at a 9Be target. Simultaneous measurements of proton emission and gamma rays were conducted using the GADGET detection system. The decay paths were carefully analyzed through beta-gamma , proton-gamma , and gamma -gamma coincidences, leading to the construction of a complete decay scheme for 23Al. The absolute beta branching ratios were determined, and log-ft values were calculated for transitions to 23Mg states. Additionally, proton branching ratios and the most precise half-life measurement of 23Al to date were obtained. The findings include the identification of 19 new gamma rays and the discovery of a new beta-delayed proton transition populating the third excited state of 22Na. |
