Asymmetry in Scattering of 150-Mev Polarized Protons in Nuclear Emulsions

Abstract

A stack of 600-micron Ilford G-5 emulsion pellicules was exposed to an integrated flux of 3 x 10/sup 3/ protons/cm/sup 2/ from the Harvard Cyclotron. The protons, of initial energy 149 plus or minus 3 Mev, emerged from the cyclotron after scattering through 15 by an interval carbon target and had an initial polarization of 72 plus or minus 3%. Results to date include a new technique for polarization measurements using nuclear emulsions, evidence on the nuclear spinorbit potential, and polarization in small-angle scattering. (W.D.M.)
