Differential cross sections and analyzing powers of the C13(p,t)C11 and C13(p,He3)B11 reactions to the ground and the first excited states were measured at Ep=65 MeV. They were analyzed by means of distorted-wave Born approximation calculations including both one- and two-step processes of p-d-t or -He3. Attention was paid to an isospin symmetry of the reaction process consisting of both isospin 0 and 1 channels, which were important in a comparable order. As intermediate states of C12 in the sequential process, five states of either isospin 0 or 1, which were strongly excited by the C13(p,d)C12 reaction, were taken into account. A good fit between the data and the theoretical values was obtained, especially for the (p,t) reactions, concerning both differential cross sections and analyzing powers. The calculations including one-step and sequential processes induced, in some cases, remarkable differences from the one-step calculation for backward angles.
