A new satellite of manganese revealed by extended-range high-energy-resolution fluorescence detection

Abstract

The discovery of a new physical process in manganese metal is reported. This process will also be present for all manganese-containing materials in condensed matter. The process was discovered by applying our new technique of XR-HERFD (extended-range high-energy-resolution fluorescence detection), which was developed from the popular high-resolution RIXS (resonant inelastic X-ray scattering) and HERFD approaches. The acquired data are accurate to many hundreds of standard deviations beyond what is regarded as the criterion for ‘discovery’. Identification and characterization of many-body processes can shed light on the X-ray absorption fine-structure spectra and inform the scientist on how t..
