Abstract

The β-decay spectroscopy on ²⁴Si was carried out in order to investigate the behavior of a weakly-bound s-wave proton. We observed two β transitions to low-lying bound states in ²⁴Al for the first time. The Gamow-Teller transition strengths B(GT) to the 1⁺ ₁ and 1⁺₂ states were deduced to be 0.13(2) and 0.14(1), which were smaller than that of mirror nucleus ²⁴Ne by 22 % and 10%, respectively. These mirror asymmetries of B(GT) indicate the configuration change in the wave function. By comparing with theoretical shell-model calculations, it is implied that the configuration change is attributed to the lowering of the Is_1/2orbital.
