Discovering hidden satellites in Mn K using novel high-accuracy fluorescence, with PCA revealing evolution of quantum processes

Abstract

We report the first experimental discovery of Hidden Satellites within the K emission lines of manganese metal (Mn,) with a total integrated statistical significance exceeding 270 (standard error), far beyond the discovery threshold. Experimental data were collected at the I20-Scanning beamline at the Diamond Light Source using our new eXtended-Range High-Energy-Resolution Fluorescence Detection (XR-HERFD) technique. The Hidden Satellites, embedded in the core emission structure, represent novel quantum many-body processes that evolve systematically as the incident photon energy increases. Principal Component Analysis (PCA) was applied to extract the major separable physical processes and va..
