微分截面为...伽马.. p.. -->.. ..伽马.. p和伽马.. p.. -->.. .. pi../从ABS测量了Super 0/P。值（t）= 0.7至4.3 GeV/sup 2/，入射能量范围为2至6 GeV。部分子模型的思想很好地描述了康普顿散射的能量依赖性。然而，能量依赖性... pi../ sup 0/光生和康普顿散射与光生的比率。pi../超0/光产生与维数计数参数不一致。
The differential cross sections for ..gamma..p ..-->.. ..gamma..p and ..gamma..p ..-->.. ..pi../sup 0/p have been measured from abs. value (t) = 0.7 to 4.3 GeV/sup 2/ and for incident energies in the range 2 to 6 GeV. The energy dependence of Compton scattering is well described by parton model ideas. However, the energy dependences of ..pi../sup 0/ photoproduction and the ratio of Compton scattering to ..pi../sup 0/ photoproduction are not consistent with dimensional counting arguments.
