Angular Dependence of Cs-137 Compton Scattering and Constraints from Energy Calibration

Open access0 citations

Abstract

This research successfully validates relativistic Compton kinematics via clear angular dependence. However, it critically exposes that profound energy calibration inconsistencies fundamentally prevent quantitative electron rest energy measurements. Deeply grateful for the guidance of Suzana Vasconcelos.
