Cross-Section Measurement of Charged-Pion Photoproduction from Hydrogen and Deuterium
(American Physical Society, 2003-06-11)
We have measured the differential cross section for the γn→π-p and γp→π+n reactions at θc.m.=90° in the photon energy range from 1.1 to 5.5 GeV at Jefferson Lab (JLab). The data at Eγ≳3.3 GeV exhibit a global scaling ...
Longitudinal Electroproduction of Charged Pions from 1H, 2H, and 3He
(American Physical Society, 2001-11-12)
Separated longitudinal and transverse cross sections for charged pion electroproduction from 1H, 2H, and 3He were measured at Q2 = 0.4(GeV/c)2 for two values of the invariant mass, W = 1.15GeV and W = 1.60GeV, in a search ...
