因瓦效应与中子散射

Invar Effect and Neutron Scattering

概述了作者十几年来用非弹性中子散射和光电子能谱等方法在非晶态因瓦合金的自旋波动力学、晶格动力学和电子结构方面所进行的实验研究．基于实验事实，提出了统一解释因瓦效应的电子－声子相互作用机制．以此展示中子散射等近代物理实验方法在凝聚态物理研究中的重要地位．

The dynamics and electronic structure of the amorphous invar alloys have been investigated by inelastic neutron scattering and X-ray photomission spectrocopy methods,respetively. Some important experimental results were obtained and, based on these results, a new mechanism of the enhanced electronphonon interaction is proposed to explain the Invar effect. The fact shows that the neutron scattering is of great importance to condensed-state physics.
