摘要

Co俘获轨道电子后形成能量为136keV的激发态，发射122keV

射线后衰变到14.4keV的能级。以122keV

射线和14.4keV

射线分别作为时幅转换的起始和终止讯号，即延迟符合技术，可测量不同延迟时间范围的穆斯堡尔谱。它可以提供很多有意义的讯息（多一个时间参数），已应用于固体物理，特别是研究迟后效应，即由

电子俘获后产生的高电荷态离子回到标准电荷态时电子的恢复率。我们测得无

Fe共振过滤辐射的时间谱是指数型的。当源和探测器间插入

Fe共振过滤器时测量了发射线和吸收线间能量差为

Δω

=0，2.5P时的延迟符合时间谱，

衰变曲线明显偏离指数型，本文作了理论分析和数据拟合。
