We extracted the differential cross section for the γn → π^- p process from a deuterium target using the CLAS detector at Jefferson Lab in Hall B for photon energies between 1.0 and 3.5 GeV and pion center-of-mass (c.m.) angles (θc.m.) between 50° and 115°. We confirm a previous indication of a broad enhancement around a cm. energy (√s) of 2.1 GeV at θc.m. =90° in the scaled differential cross section, s⁷ σ/dt and a rapid fall-off in a center-of-mass energy region of about 400 MeV following the enhancement. Our data show an angular dependence of this enhancement as the suggested scaling region is approached for θc.m. from 70° to 105°. © 2009 American Institute of Physics.
