We carried out the β-decay spectroscopy on 24Si in order to investigate a change in configuration in the wave function induced by Thomas-Ehrman shift from a perspective of mirror asymmetry of B(GT). We observed two βtransitions to low-lying bound states in 24Al for the first time. In this proceeding, the B(GT) of 24Si is compared with that of the mirror nucleus 24Ne, and the mirror asymmetry of B(GT) is determined. Then the origin of the B(GT) asymmetry is discussed through the comparison with theoretical calculations.
