We present differential cross sections and complete sets of polarization-transfer coefficients, Dij, obtained in the 13C(p→,n→)13N reaction studied at 197 MeV incident proton energy and laboratory angles between 0° and 33°. These complete sets of polarization observables are used to obtain spin-longitudinal and spin-transverse components for transitions to the ground state, to the first, and to the unresolved second and third excited states in 13N at 2.36 MeV and (3.50+3.55) MeV, respectively. The results are used to obtain the two ΔJπ contributions for the ground and first excited state transitions and are compared with corresponding distorted-wave impulse approximation (DWIA) calculations. In particular, empirical angular distribution values for the unique spin-longitudinal ΔJ=0- transition to the first excited state in 13N are obtained and compared with DWIA calculations.
