We measured the reaction cross sections (σR) and parallel momentum distributions (P//) of 23Al and it's neighboring nuclei at RIKEN-RIPS. An enhanced σR of 23Al is observed, which is consistent with the previous experimental result. And the P// of fragment from the projectile breakup nuclei have been obtained at the same time. We discuss our experimental data under the Few-Body Glauber Model. The P// of 23Al shows the ground state of the valence proton is a d-wave, which is consistent with the recent measurement of 23Al's g factor. To explain the experimental σR and P// of 23Al at the same time, we suggest an enlarged core of 23Al.
