A calculation of the single scattering contribution to the differential cross-section for the elastic scattering of 25-100 MeV positive pions by deuterium McMillan, Malcolm; Landau, Rubin H.

Abstract

We have performed a numerical study of the single scattering contribution to the differential cross-section for the elastic scattering of 25-100 MeV positive pions by deuterium. In particular, we have examined effects due to the presence of the D-state component of the deuteron wave function, to internal motion of the target nucleons, and to uncertainties in the off-energy-shell pion-nucleon scattering amplitudes and the pion-nucleon phase shifts. Our results encourage further experimental and theoretical study of pion-nucleon and pion-deuteron scattering. They also encourage an experimental and theoretical study of π± - ³He elastic scattering as a means of investigating ³He wave function components.
