Angular distributions of the /sup 25/Mg(p,t)/sup 23/Mg reaction have been measured at 40 MeV bombarding energy. An energy resolution of 10--15 keV permitted the observation of about 40 new levels in /sup 23/Mg up to 9.72 MeV of excitation. Unambiguous spin and parity assignments of 5/2/sup +/ are made to the levels at 0.045(3), 5.662(8), 6.566(8), 6.899(5), 6.982(5), 7.582(6), 7.795(6), and 8.155(6) MeV on the basis of an L=0 admixture in the angular distributions. Values of the orbital angular momentum L transferred to several states have been deduced. Microscopic distorted-wave Born-approximation calculations for the transitions to the first eight 5/2/sup +/ states have been performed using spectroscopic amplitudes from recent shell model calculations and are compared to the experimental data.
