Estimation of isospin effects in nucleon-4He scattering

Abstract
Within the framework of a very simple Glauber model treating the centre-of-mass effects exactly, we investigate the effect of neutron-proton density differences in the nucleus 4He on the 800 MeV nucleon-4He elastic scattering cross section at small transfers. From the results, a method of obtaining an absolute calibration of a neutron beam is proposed
