论文摘要
本文研究了一系列分子中正电子歼灭过程的伽马射线光谱。结果表明，分子的平均价电子能与伽玛射线光谱的一半最大（FWHM）的完整宽度有线性相关。此外，我们定义了一个新的物理量平均多普勒移位（AD），可以用作描述伽马射线光谱的特征的特征值。由于广告包含有关伽马射线光谱的所有信息，因此它可以更准确地表示伽马射线光谱的特性。对于一系列分子，本文比较了其伽马射线光谱的AD和FWHM和平均价电子能量。结果表明，ADS与平均价电子能量和FWHM具有线性相关性。此外，这证明歼灭主要发生在价电子上，并且还说明了广告具有一定的适用性。预计这将为我们提供对正电子歼灭过程的更深入的了解。
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 a linear correlation with the full width at half maximum (FWHM) of the gamma-ray spectra. In addition, we defined a new physical quantity Average Doppler Shift (ADS), which can be used as the eigenvalue to describe the characteristics of the gamma-ray spectra. Since ADS contains all the information about the gamma-ray spectra, it can more accurately represent the characteristics of the gamma-ray spectra. For a series of molecules, this paper compares the ADS and FWHM of their gamma-ray spectra and the average valence electron energy. The results show that ADS has a linear correlation with the average valence electron energy and the FWHM. Further, this proves that the annihilation mainly occurs on valence electrons, and it also illustrates that the ADS has certain applicability. It is expected that this will provide us with a deeper understanding of the positron annihilation process.
