The aim of this project is the development of the measurement system for synchrotron-radiation (SR) based Mossbauer spectroscopy of Neodymium and Ytterbium. Mossbauer spectroscopy is a method for the study of element-specific electronic states even in compounds composed of many elements. Both Neodymium and Ytterbium is rare-earth elements and they often have important function for many materials such as magnetic materials. However, the traditional Mossbauer spectroscopy with radioactive isotopes (RI) as gamma-ray source has difficulty in the preparation of the RI. To solve this difficulty, SR can be used. To achieve SR based Mossbauer spectroscopy of these two elements, the components of the measurement system was developed. As a result, the drastic enhancement of the detected counting rate in SR based Mossbauer spectroscopy of Ytterbium is achieved, and also the counting rate of about 1.5 count per second is achieved in nuclear reosonant scattering of SR by Neodymium.
