On the Measurement of Visco-Elastic Properties of Matters by the Mossbauer Effect

概要

論文の詳細を見る
A technique to measure the visco-elastic properties of materials by using the Mossbauer effect is proposed. Assuming that a spring coil specimen is attached to the transducer of Mossbauer spectrometer, which gives a sinusoidal Doppler motion between the gamma ray source and the absorber, the visco-elastic vibration of the specimen is calculated and the mechanical resonance conditions are found. When the gamma ray source and absorber are connected to the visco-elastic system, the Mossbauer pattern will be subjected to a modulation, from which the elastic constant and the viscosity of the specimen can be measured, especially from the mechanical resonance condition. A variety of ways of connection between the mechanical and Mossbauer system are considered and applications of the technique are discussed.
