Abstract：
The longitudinal momentum distribution (P_//) of fragments after one-proton removal from²³Al and reaction cross sections (σ_R) for^23,24Al on carbon target at 74A MeV have been measured simultaneously. An enhancement in σ_Ris observed for²³Al compared with²⁴Al. The full width at half maximum of the P_//distribution for²²Mg fragments has been determined to be 232±28 MeV/c. Analysis of P_//using the Few-Body Glauber Model indicates a dominant d-wave configuration for the valence proton in the ground state of²³Al. The exotic structure in²³Al is discussed.
