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…
Calculations of gamma-ray spectral profiles of linear alkanes in the positron annihilation process
X. G. Ma, F. Wang
The positron-electron annihilation gamma-ray spectra of linear alkanes CnH2n+2 (n=1-12) have been studied systematically. A profile quality (PQ) parameter, is introduced to assess…
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…
Gamma-ray spectra of hexane in gas phase and liquid phase
Xiaoguang Ma, Feng Wang
Theoretical gamma-ray spectra of molecule hexane have been calculated and compared with the experimental results in both gas (Surko et al, 1997) and liquid (Kerr et al, 1965) phase…
