Abstract：
The longitudinal momentum distribution (P_//) of fragments after one-proton removal from ²³Al and reaction cross sections (σ_R) for ^23,24Al on carbon target at 74A MeV have been measured simultaneously. An enhancement in σ_R is observed for ²³Al compared with ²⁴Al. The full width at half maximum of the P_// distribution for ²²Mg 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 of ²³Al. The exotic structure in ²³Al is discussed.
