Measurement of the Spin-Rotation Parameterβin Proton-He4Scattering at 48 MeV

Abstract

The spin-rotation parameter 0 has been measured at nine scattering angles between 11° and 90° (lab) in proton-He 4 elastic scattering at 48 MeV, using the polarized proton beam from the Proton Linear Accelerator at the Rutherford High Energy Laboratory, Chilton, England. The results are in good agreement with the predictions of the 40-MeV phase shift analysis of Giamati, Madsen, and Thaler.
