利用基于陷阱的高分辨率正电子束,我们测量了正电子在水蒸气中的弹性和非弹性散射。测量包括微分弹性、全弹性和全非弹性(不包括正电子形成)的绝对横截面。所研究的能量范围从1 eV到60 eV。用R-矩阵和扭曲波计算,以及我们自己应用的正电子相互作用的独立原子模型,与理论进行了比较。
Utilising a high-resolution, trap-based positron beam, we have measured both elastic and inelastic scattering of positrons from water vapour. The measurements comprise differential elastic, total elastic, and total inelastic (not including positronium formation) absolute cross sections. The energy range investigated is from 1 eV to 60 eV. Comparison with theory is made with both R-Matrix and distorted wave calculations, and with our own application of the Independent Atom Model for positron interactions.
