Abstract
Polarization of protons in proton-helium scattering may be calculated from phase shifts obtained from differential cross section measurements. Calculations of this type were performed for energies up to 18 Mev. On the basis of these results, an instrument was built with which proton polarizations could be measured for protons with energies from 5 Mev to 18 Mev and beyond. A second polarization analyzer was built utilizing the discovery of polarization in the scattering of protons by carbon around 17 Mev. Results are given for polarization measurements on H, D, Be, C, and Al near 18 Mev. Angular distributions for polarization in both elastic and inelastic (4.4-Mev excitation) scattering by carbon are also reported.
