抄録

Proton resonances in 23Al have been investigated for the first time by the resonant elastic and inelastic scattering of 22Mg+p by using a 4.38 MeV/nucleon 22Mg beam bombarding a thick Hydrogen target. The low-energy 22Mg beam was separated by the CNS radioactive ion beam separator (CRIB). A new resonant state due to elastic scattering was observed at Ex = 3.00 MeV with a Jπ = (3/2+) assignment. Other three excited states due to resonant inelastic scattering at 3.14, 3.26 and 3.95 MeV were identified and all mainly decay to the first excited state in 22Mg by the proton emissions. The newly observed 3.95-MeV state probably has a spin-parity of Jπ = (7/2 +). The resonant properties were determined from an R-matrix analysis of the excitation functions. The weak-coupling structure in 23Al is discussed in conjunction with a shell-model calculation.
