[en] The ¹²C(d, p) ¹³C reaction has been studied at Esub(d) = 30 MeV. All the known positive-parity states of ¹³C below 10 MeV in excitation energy, including the 7/2⁺ and 9/2⁺ states, are observed in this reaction. The angular distributions for these positive-parity bound and unbound states are analyzed in CCBA frame work. The ¹³C wave functions, which reproduce the resonant and non-resonant scattering of neutrons from ¹²C, also give good accounts of the experimentally observed angular distributions and energy spectra of outgoing protons in the ¹²C(d, p) ¹³C reaction. In most cases the cross section magnitude and the angular distribution shape are primarily determined by the 0⁺ x j component, even if it is only a small fraction of the total wave function. An exception is the 7/2⁺ state, where the main contribution comes from the 2⁺ x dsub(5/2) component. The inclusion of the 4⁺ state in ¹²C and the gsub(9/2) and gsub(7/2) neutron components in the n + ¹²C system has very small effects on the low-spin states, but is indispensable for a good fit to the 7/2⁺ and 9/2⁺ angular distributions. The transitions to the negative-parity states, 1/2₁^-, 3/2₁^-, 5/2^-, 7/2^- and 1/2₃^-, are also observed experimentally, and analyzed by DWBA. (author)
