$sup 20$Ne($sup 3$He,n)$sup 22$Mg at $sup 3$He energies between 2.6 and 4.0 MeV
The /sup 20/Ne(/sup 3/He,n) reaction leading to the ground state of /sup 22/Mg was investigated in the /sup 3/He/sup +/ energy range of 2.6 to 4.0 MeV. Angular distributions were determined with a neutron time-of-flight spectrometer at average incident energies (lab) of 3.27, 3.69, and 4.01 MeV between 0 deg and 12 deg (lab). Excitation functions for the energy region were measured at 0 deg and 80 deg (lab). The observed differential cross sections are explained by coherent contributions from direct interaction and compound-nucleus formation. A spectroscopic factor was extracted for the DWBA calculation from the absolute cross-section measurements and found to be S = 0.43 plus or minus 0.21. Resonances in the compound-nucleus formation were found at 3.00 and 3.33 MeV (c.m.) with widths of 0.28 and 0.21 MeV and spins of 5/2+ and 1/2-, respectively. (auth)
