    The differential cross section dσ/dt for the photoproduction processes of γn→π-p and γp→π+n at θc.m.=90° with photon energies from 1.1 to 5.5 GeV was measured. The data with Eγ≳3.3GeV exhibited a global scaling behavior in both processes, consistent with the constituent counting rule. Furthermore, the scaled cross section data showed an enhancement at a center-of-mass energy near 2.2 GeV and the exact nature of such a structure requires further investigation.
