Cross sections for the reaction 13C(p, d)12C* in coincidence with back-to-back, out-of-plane, two-proton decays at high excitation energies (140-420 MeV) are presented for Ep = 800 MeV at deuteron laboratory angles of 2.5°, 5.0°, and 9.0°. At all angles a resonant-like enhancement in the cross section is observed at 241 MeV of excitation energy with a width of 55 MeV. Some features of these data indicate that this structure may be related to the formation of low-spin (ΔN-1) states in 12C.
