新型数据分析工具用于评估正电子-电子湮灭谱的重叠多普勒展宽线
摘要：Coincidence Doppler Broadening Spectroscopy (CDBS) of the 511 keV annihilation line reveals the elemental signature at the annihilation site in matter. CDBS enables the analysis of foreign atoms in the host matrix, vacancy-solute complexes, and precipitates in solids. We developed a modular python-based open source software solution for the reliable extraction of the annihilation line using CDBS data. The software provides ratio curves highlighting the elemental signature in the spectra and allows the readout and averaging of multiple detector pairs. Additionally, we implemented an improved algorithm to significantly reduce the background at high Doppler shifts.
