We carried out the beta-decay spectroscopy on {sup 24}Si 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 beta transitions to low-lying bound states in {sup 24}Al for the first time. In this proceeding, the B(GT) of {sup 24}Si is compared with that of the mirror nucleus {sup 24}Ne, 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.
