Double Scattering Experiment with 96-Mev Protons

Abstract

By using 96-Mev protons, a double scattering experiment has been performed with a variety of targets and scattering angles. The observed values of the asymmetry $e$ in the intensity of the second-scattered beam are small. For instance with carbon as a first and second scatterer, and scattering angles of 20° the observed value of $e=+3.6\mathrm{}\pm 1.6$ percent. It is concluded that the polarization $P$ decreases rapidly with decreasing energy below 130 Mev.
