In this paper, we present differential cross sections and complete sets of polarization transfer coefficients, D i j , obtained in the 13 C(p ជ ,n ជ) 13 N reaction studied at zero degree and at 197 MeV incident proton energy. The complete set of polarization observables is used to obtain the Fermi and Gamow-Teller ͑GT͒ cross section contributions in the ground state transition, which are then used to deduce GT transition strengths. The sum of the GT strength up to 20 MeV of excitation is compared with shell model calculations. In the region between 20 to 46 MeV of excitation, the differential cross section has been separated in spin and nonspin components.
