Proton-neutron electron-positron pair production cross sections are calculated in the framework of the pseudoscalar one-pion exchange model in a fully relativistic manner.
A computer program has been developed to evaluate invariants and Dirac traces for a given data point.
The sections for symmetric coplanar events for laboratory kinetic energies of 10 to 250 MeV were calculated for pair angles of 20° to 120°.
Frequency distributions were also calculated, at a laboratory energy of 200 MeV, using a random number generator to select data points. The frequency distributions are illustrated by curves.
It was noted that the inclusion of heavier bosons will not significantly improve the results at laboratory energies less than 200 MeV.
