STRUCTURE OF C-14 STUDIED BY THE C-14(P,D)C-13 REACTION

Cross sections for the neutron pickup reaction 14C(p, d)13C were measured at Ep = 35.0 MeV for the states below E = 10 MeV, and at Ep = 40.1 MeV for the states between Ex = 11 and 18 MeV. Obtained angular distributions were compared with exact finite-range DWBA calculations to extract spectroscopic factors. Second-order DWBA calculations were also made in some cases. Almost full 0p 1 2 strength was found, while the observed 0p 3 2 strength was 80% of the simple sum-rule limit. The main part of the remaining strength was found in the 0d 5 2 orbit, and, in a lesser degree, in the 1s 1 2 and 0d 3 2 orbits. Small fractions of the 0f 5 2 and Og 9 2 strengths were also necessary to explain the angular-distribution shapes and the cross-section magnitudes of the predominantly multistep transitions to the 5- 2 and 5+ 2 states. © 1990.
