| Popis: | Photoprotons with energies above 120 Mev have been studied at the M.I.T. synchrotron. Angular distributions of protons with 126 Mev, 169 Mev, and 203 Mev were obtained in the angular range from 20\ifmmode^\circ\else\textdegree\fi{} to 160\ifmmode^\circ\else\textdegree\fi{} from both beryllium and carbon targets. These observations showed that the protons in a Be and in a C nucleus behave identically in high energy photoproton production. The energy distribution of photoprotons from carbon at 30\ifmmode^\circ\else\textdegree\fi{} was investigated in particular detail. A break is observed in the energy distribution which appears to be in accordance with Levinger's "quasi-deuteron model." Absolute values for the differential and total cross sections were obtained.A detailed analysis of existing data is given which raises the possibility that the agreement with the "quasi-deuteron model" may be fortuitous. |
