CHARGE-EXCHANGE NP SCATTERING

摘要

We have studied the charge-exchange p(n,p)n reaction for neutron beam momenta from 0.605 to 105 GeV/c. The t-matrix is constructed using a one-pion-exchange plus rho-exchange transition potential. The differential cross sections are calculated in the distorted wave Born approximation and are compared with the available experimental data. The data on the t-distributions upto 20 GeV/c are reproduced well within our model at all values of the momentum transfer t. [References: 44]
