穆斯堡尔谱镜像折叠新方法

摘要

Usually， for Mssbauer mirror spectra folding procedure is an effective way to eliminate the geometric effect of the base line， and to raise the data acquisition efficiency. Folding is often proceeded by taking the center of mirror spectra as folding point， but a disadvantage of obvious line-broadening， resulted by the fact that the Doppler velocity lags behind the drive signal is usually overlooked. In this paper， a new approach was developed， which could avoid the above problem.%通常，对穆斯堡尔镜像谱折叠是消除基线几何效应的有效方法，数据获取效率也有所提高。介绍了一种新的折叠方法，解决了折叠过程中一般以谱线中心作为折叠点，而没有考虑到多普勒速度落后于驱动信号，这种方法会带来明显的线宽加宽的问题。
