Abstract
The polarizations of photoprotons from Li, Be, B, and C were measured by means of a counter polarimeter at proton production angles of 45°, 56°, and 90° in the laboratory system. The photon source was the bremsstrahlung from the Purdue synchrotron operating at a peak energy of 335 MeV. The observed protons had energies in the range 135 to 200 MeV. The left-right asymmetry of scattering of the photoprotons in a carbon analyzer was used to determine their polarization. The observed polarization was small and is consistent both with a zero value and with the theory. A qualitative discussion in terms of quasi-deuteron and isobar models is given.
