Zero degree polarization transfer measurements for the C-13((p)over-right-arrow,(n)over-right-arrow)N-13 reaction at 197 MeV and empirical Gamow-Teller strength distribution - art. no. 024608

In this paper, we present differential cross sections and complete sets of polarization transfer coefficients, D-ij, obtained in the C-13((p) over rig ht arrow, (n) over right arrow)N-13 reaction studied at zero degree and at 197 MeV incident proton energy. The complete set of polarization observable s is used to obtain the Fermi and Gamow-Teller (GT) cross section contribut ions in the ground state transition, which are then used to deduce GT trans ition strengths. The sum of the GT strength up to 20 MeV of excitation is c ompared with shell model calculations. In the region between 20 to 46 MeV o f excitation, the differential cross section has been separated in spin and nonspin components.
