Abstract
The polarization in p-He4 elastic scattering has been measured between 0.56 and 1.73 GeV in a range of the square of the four-momentum transfer between 0.006 and 1.2 (GeV/c)2. The data are characterized by positive polarization maxima at -t near 0.08 and 0.36 (GeV/c)2. At 0.56 GeV, a sharp peak of large negative polarization at 0.23 (GeV/c)2 is observed. This structure persists at higher bombarding energies, but is no longer negative and becomes increasingly shallower as the bombarding energy increases to 1 GeV and then is relatively unchanging.
