Excited states up to about 18 MeV in 12C have been investigated with the 13C(p,d) 12C reaction. It was found that five states (ground, 0+, T=0; 4.43 MeV, 2+, T=0; 12.71 MeV, 1+, T=0; 15.11 MeV, 1+, T=1 and 16.11 MeV, 2+,T=1 almost exhaust the available pick-up strength. Spectroscopic factors for these states extracted from a DWBA analysis with the usual separation energy procedure gave good agreement with the prediction of the effective interaction calculation by Cohen and Kurath. © 1968.
