Neutron pickup from 22Ne

Levels below 10 MeV in 21Ne have been investigated with the 22Ne(3He,α) reaction at a bombarding energy of 15 MeV, with an enriched gas target. Angular distributions were extracted for twenty-six levels (or groups of levels). Only two levels of each J/sup [/<1/2+, 3/2+, and 5/2+ have spectroscopic factors larger than 0.03. Results for positive-parity states are in good agreement with shell-model calculations in an (sd)5 basis. But the presence of additional levels above 6 MeV, not present in the shell-model calculation, suggests core excitation is important for the positive-parity states above that energy. The 1/2- state at 2.79 MeV has only about half the strength expected for a pure 6p-1h state, with T/sub p/<1. Very little 1patsub 3/2at pickup is observed below 10 MeV excitation
