我们开发了一种使用同步辐射 (SR) 产生穆斯堡尔吸收光谱的新方法;该方法适用于几乎所有穆斯堡尔核素,包括那些无法通过以前使用放射​​性同位素 (RI) 源的方法测量的核素。 73Ge 68.752 keV 激发态的穆斯堡尔谱无法使用 RI 源进行测量,但使用 SR 进行了测量。我们的结果表明,由于 SR 的优异特性,该方法可用于执行先进的穆斯堡尔光谱测量。
We have developed a new method that yields Mössbauer absorption spectra using synchrotron radiation (SR); this method is applicable for almost all Mössbauer nuclides including those that cannot be measured by previous methods using radioisotope (RI) sources. The Mössbauer spectrum of the 68.752 keV excited state of 73Ge, which cannot be measured using a RI source, was measured using SR. Our results show that this method can be used to perform advanced Mössbauer spectroscopy measurements owing to the excellent features of SR.
