Abstract
A brief description is given of a new facility that permits Fe-57 Moss bauer spectroscopy (MS) studies in transmission geometry to be made in the range 10-300 K on absorbers pressurized in a diamond-anvil cell. Examples are given of good quality spectra which have each been obtain ed in 20-30 hours by using a ''point'' source of similar to 5 mCi in c onjunction with absorbers that have a comparatively low-enrichment (10 -20%) of Fe-57. The successful execution of Fe-57 MS at high pressures and variable cryogenic temperatures has been achieved by making simpl e refinements to existing elements of high-pressure MS methodology. Th e facility described herein finds important application in fields of g eophysics and condensed matter physics.
