一般情况下,人们都把原子核简单地看作为,具有磁矩、质量或有放射性衰变的一颗带正电荷的粒子,但是,穆斯堡尔谱仪中,却扩展利用了原子核的特性,从而获得了关于原子核周围环境的详细信息。这种谐仪与磁共振谱仪一样,有提供固体中对于局部磁场电场信息的能力。穆斯堡尔谱仪是“利用穆斯堡尔效应”制成的。这个效应的基础是无后座力的跃迁现象。 本文先叙述贝基本原理,随后介绍谱仪的结构,然后,以57Fe为特例说明影响穆斯堡尔谱的三个因素:
In general, nuclei are simply regarded as a positively charged particle with a magnetic moment, mass, or radioactive decay. However, in the Mössbauer spectroscopy, the characteristics of the nucleus are expanded to Get detailed information about the environment surrounding the nucleus. Like the magnetic resonance spectrometer, this type of harmonic instrument offers the ability to provide information about the electric field in a local field in a solid. The Mössbauer spectrometer is made “using the Münster effect.” The basis of this effect is the absence of recoil transitions. This article begins with a description of the basics, and then introduces the structure of the spectrometer. Then, using 57Fe as a special case, we illustrate three factors that affect the Mössbauer spectrum:
