Measurement of the helicity asymmetry E for the reaction $$$$ \gamma p\rightarrow \pi ^0 p$$$$: The CBELSA/TAPS Collaboration
Abstract
Abstract A measurement of the double-polarization observable E for the reaction $$$$\gamma p\rightarrow \pi ^0 p$$$$ is reported. The data were taken with the CBELSA/TAPS experiment at the ELSA facility in Bonn using the Bonn frozen-spin butanol (C $$$$_4$$$$ H $$$$_9$$$$ OH) target, which provided longitudinally-polarized protons. Circularly-polarized photons were produced via bremsstrahlung of longitudinally-polarized electrons. The data cover the photon energy range from $$$$E_\gamma =600$$$$ to 2310 MeV and nearly the complete angular range. The results are compared to and have been included in recent partial wave analyses.
