摘　　要：本文回顾极化电子与分子碰撞中的手征效应研究进展。着重描述电子二色性的特征、理论背景。In this report we review the experimental and theoretical development in the study of chiral-effects in electron-molecule scattering. The concept of chirality plays an important role in many domains of science, for example elementary particles, life sciences and pharmacology. The goal of the investigations, reviewed here, is the basic understanding of starting with simplest possible physics process, namely elastic collisions between polarized low-energy electrons and chiral molecules, and then to try to understand this process in depth as a starting point for further research of more complex case. The experimental result demonstrates recently that an electron dichroism does exist.
