An experimental study of the 24Mg(p, n)24Al reaction at Ep = 35 MeV was carried out. High-resolution neutron time-of-flight spectra were measured at 17 angles in a range of 0°-110°. Neutron peaks corresponding to seventeen states in 24A1 have been resolved. A number of spin-parity assignments have been made based on distorted-wave Born-approximation (DWBA) analyses for the measured angular distributions, using microscopic transition amplitudes obtained from the 1s0d shell model for positive-parity states and those from the 0s0p-1s0d-1p0f open-shell randomphase approximation (OSRPA) for negative-parity states. Reasonable correlation between the low-energy (p, n) cross section and the β-decay strength has been found for the observed 0+ →1 + Gamow-Teller transitions leading to the 0.439, 1.116 and 3.023 MeV states in 24Al. The 1.56 MeV 5+ state has been identified as a 0 h {combining short solidus overlay}ω stretched state, in addition to the 5.54 MeV, 6 state of 1 h {combining short solidus overlay}ω character. Candidates for the 1 h {combining short solidus overlay}ω negative-parity transitions leading to the 2, 3, 4 states are also presented.
