Average Doppler Shift of Gamma-ray Spectra of Positron Annihilation Process in Molecules
Fang Yuan, Xiaoguang Ma, Yu Wu +1
This paper studies the gamma-ray spectra of positron annihilation processes in a series of molecules. The results show that the average valence electron energy of the molecules has…
An alternative indicator of annihilated electrons in atoms: Rahm's electronegativity scale
Yu Wu, Xiaoguang Ma, Fang Yuan +3
This paper presents a new explanation of the width of gamma-ray spectra based on Rahm's electronegativity scale. This quantitatively proves, for the first time, that positrophilic…
Gamma -ray spectra in the positron-annihilation process of molecules at room temperature
Lin Tang, Xiaoguang Ma, Jipeng Sui +2
In this study, a fully self-consistent method was developed to obtain the wave functions of the positron and electrons in molecules simultaneously. The wave function of a positron…
Docking positrophilic electrons into molecular attractive potential of fluorinated methanes
Xiaoguang Ma, Feng Wang
The present study shows that the positrophilic electrons of a molecule dock into the positron attractive potential region in the annihilation process under the plane-wave approxima…
