Abstract

The longitudinal momentum (p_//) distributions of fragments after one-proton removal and reaction cross sections (σ_R) for several N = 10 isotones at intermediate energy (∼ 70A MeV) have been measured simultaneously at the RIken Projectile fragment Separator (RIPS), p_// was measured using a direct time-of-flight (TOP) technique, while σ_R was determined using a transmission method. An enhanced σ_R is observed for ²³Al comparing with its neighbors. The p_// distribution for ²²Mg fragments from ²³Al one-proton removal reaction has been obtained for the first time. The experimental data are discussed within a Few Body Glauber (FBG) framework. Analysis of p_// indicates a dominant d-wave component in the ground state of ²³Al. This agrees with recent experimental results. We also suggest the possibility of an enlarged ²²Mg core for proton-rich nucleus ²³Al.
