The Q^2 Evolution of the GDH sum Rule (on 3He and the Neutron)
Conference
·
OSTI ID:903200
We discuss the extention of the Gerasimov-Drell-Hearn (GDH) sum rule, which pertains to real photons, to include scattering due to virtual photons. We present data from Jefferson Laboratory experiment E94-010 which measured the inclusive scattering of polarized electrons from a polarized 3He target over the quasielastic and resonance regions. From these data we exctract the transverse-transverse interference cross section {sigma}{prime}_TT', and compute the Q^2 depenent extended GDH integral.
