An alternative indicator of annihilated electrons in atoms: Rahm's electronegativity scale

This paper presents a new explanation of the width gamma-ray spectra based on Rahm's electronegativity scale. quantitatively proves, for first time, that positrophilic electrons in positron-electron annihilation process are exactly valence electrons. suggests replacement Full Width at Half Maximum (FWHM) with newly defined physical quantity Average Doppler Shift (ADS). Both FWHM and ADS light elements agree well corresponding values, respectively. Further, provides strong evidence favor It is expected this will be useful understanding mechanism process.
