Measurements of the Polarization in Proton-Helium Elastic Scattering

Abstract
The polarization of protons elastically scattered by helium was measured by the double scattering method. Incident proton or alpha-particle beam was obtained from the INSJ 160 cm variable energy cyclotron. Three interdependent measurements, in which the polarization product was equal to P 1 P 2 , P 2 P 3 or P 3 P 1 were made. The following results were obtained:
