SUMMARY This excellent data set provided: Good control of systematics Wide range of results: - Total cross sections for 11 energy bins - HyCal Solid Angle cross sections (11 energy bins) - Differential cross sections 15 angle bins for each energy Results compare very well with theory Improvements: Simulation of the background would help to: - reduce systematic uncertainties - increase control of systematics Compton Review November 30, 2018
