Polarized Target Asymmetry For Neutral Pion-Photoproduction From Protons In Photon Energy-Range 0.7-1.45gev
NUCLEAR PHYSICS B(1977)
摘要
Measurements have been made of the target asymmetry parameter for photoproduction of π0 mesons from protons, using a butanol polarised target with a 3He cryostat. Results were obtained at 14 incident photon energies between 0.7 GeV and 1.45 GeV over an angular range ∼40° to 145° c.m. The recent analysis of Barbour and Crawford provides a very good fit to the data.
