Interactive positronfit: A new version of a program for analysing positron lifetime spectra

Title of program: INTERACTIVE POSITRONFIT
Catalogue Id: AAHI_v1_0

Nature of problem
Positrons annihilate in condensed matter from different states (e.g., from defect traps in metals) so that a measured lifetime spectrum consists of a sum of exponential decay components smeared with the instrumental resolution function and superimposed on a constant background. Experimenters want to extract the lifetimes and intensities of the annihilation from different states.

程序标题：交互式正电子拟合

目录编号：AAHI_v1_0

问题性质
正电子在凝聚态物质中从不同状态（例如，从金属中的缺陷陷阱）湮灭，导致测量的寿命谱由指数衰减成分的总和组成，这些成分被仪器分辨率函数所展宽，并叠加在恒定背景之上。实验者希望从不同状态中提取湮灭的寿命和强度。
