B11(p, n)C11(0)Polarization-Transfer Measurement at 0° and the Effective Two-Nucleon Interaction

Abstract
The transverse polarization transfer coefficient, Kvy(0°) has been measured for the reaction B11(p, n)C11(0) at EP=16.3, 21.3, and 26.5 MeV. The results are not in agreement with direct-reaction-theory calculations using an empirical charge-exchange effective interaction which includes both central and tensor forces.
