Absolute calibration of spin [formula omitted] polarization

It is shown that the polarization P( θ, E) of spin − 1 2 particles scattered from particles without spin must reach the value | P| = 1 at some point ( θ 1, E 1), if the scattering amplitudes fullfill certain conditions at two other energies E 0 < E 1 and E 2 > E 1. As examples, nucleon- 4He an...

Description
Summary:It is shown that the polarization P( θ, E) of spin − 1 2 particles scattered from particles without spin must reach the value | P| = 1 at some point ( θ 1, E 1), if the scattering amplitudes fullfill certain conditions at two other energies E 0 < E 1 and E 2 > E 1. As examples, nucleon- 4He and 3He 4He elastic scattering are investigated in this respect.
