英文摘要	The longitudinal momentum distribution (P//) of fragments after one-proton removal from²³Al and reaction cross sections (σR) for^23,24Al on carbon target at 74AMeV have been measured using 135AMeV²⁸Si primary beam on RIPS in RIKEN. P//is measured by a direct time-of-flight (TOF) technique, while σRis determined using a transmission method. An enhancement in σRis observed for²³Al compared with²⁴Al. The P//for²²Mg fragments from²³Al breakup has been obtained for the first time. FWHM of the distributions has been determined to be 233±14 MeV/c. The experimental data are discussed by use of the Few-Body Glauber Model (FBGM). Analysis of P//indicates a dominant d-wave configuration for the valence proton in the ground state of²³Al. The possibility of an enlarged²²Mg core for proton-rich nucleus²³Al is demonstrated. © 2008 World Scientific Publishing Co. Pte. Ltd.
