摘要：

The utilization of cryogenerators for Mössbauer measurements at low temperature may give trouble owing to the velocity noise caused by spurious vibrations. A theoretical analysis of the velocity noise effect and a way of handling it has already been carried out by the authors. The present work concerns the applications of the theoretical method and illustrates the results obtained applying it to the spectra collected with a new Mössbauer cryostat cooled by a Gifford-McMahon closed cycle refrigerator. © 1990 J.C.
