The Polarization of Protons Elastically Scattered from Oxygen at 8.7 MeV

A polarized proton beam has been obtained by inserting an internal graphite target in the cyclotron and using the polarization properties of the reaction 12C(d, p)13C. By scattering this beam from an ice target, the elastic scattering polarization from oxygen was determined at a number of angles. The results show some similarity to the predictions of the optical model but there is evidence of a rapid variation of the polarization with energy.
