The reaction 12C(t, p)14C has been investigated with an 18 MeV triton beam. Twenty energy levels of 14C were identified up to 13 MeV excitation. Angular distributions were measured and compared with DWBA calculations. A previously unreported 0+ level at 9.75 MeV was observed; it undoubtedly corresponds to the second predominantly sd shell 0+ state in 14C. Additional spin and parity assignments have been made in the present work: 9.81 MeV, (1-); 10.43 MeV, 2+; 10.50 MeV, (3-); 10.74 MeV, 4+; 11.40 MeV, 1-; 11.67 MeV, (1-); 11.73 MeV, (5-); 12.58 MeV, (2+, 3-); 12.87 MeV. 2+, 3-; and 12.96 MeV, (1-); none of which had a definite spin and parity assignment previously. Our results confirm the previous information on the level structure of 14C below 8.5 MeV. The cross section for the unnatural parity state at 7.34 MeV, Jπ = 2-, is well reproduced by a two-step reaction calculation. The results are compared with the predictions of a weak coupling model.
