Mechanism ofNe20(t,p) and nuclear structure ofNe22

In the [sup 20]Ne([ital t],[ital p])[sup 22]Ne reaction at a bombarding energy of 15 MeV, excitation energies have been measured for 81 levels up to [ital E][sub [ital x]]=13.4 MeV. Thirteen new levels were identified. Distorted-wave Born-approximation (DWBA) calculations with spherical and deformed potentials were used to analyze the angular distributions. Two-step processes were found to make important contributions to the reaction. For most low-lying positive-parity levels, results are analyzed with two-particle transfer amplitudes from a realistic shell-model calculation. We have assigned spin-parities to 42 levels above 6.6 MeV based on the success of the DWBA analysis.
