Abstract

The reaction cross sections and momentum distributions for 23Al and its neighbouring nuclei have been measured at the Riken Projectile Fragment Separator (RIPS). The primary beam of 135 A MeV 28Si was used to produce the secondary beams. The measurement of σR was carried out by using a transmission-type method, σR was determined by the ratios between incident and outgoing particles without reaction from both target-in and target-out measurements. P// of fragment from breakup reactions was determined from the measured TOF between F2 and F3. An enhancement is observed in σR for 23Al compared to its neighbors. The P// of 22Mg fragments from 23Al breakup have been obtained. The width of the distributions is found to be consistent with prediction by the Goldhaber Model. The experimental data are discussed in the framework of Glauber model. The analysis of P// indicates a dominant d-wave component in the ground state of 23Al. This confirms the result of a recent magnetic moment measurement which indicates that the valence proton is in d-wave.
