Very high pressure Mössbauer Spectroscopy using Diamond Anvil Cells

The technique of generating very high pressure by means of Diamond Anvil Cells (DAC) for Mössbauer Effect applications is outlined. A comprehensive description is presented of the principles of DAC, modification for the use in Mössbauer Spectroscopy (MS), the Merrill-Bassett and Bassett cells, of pressure measurements, of gasketing and collimation, and of hydrostatic media. Examples of¹⁵¹Eu,¹¹⁹Sn and¹²⁹I are given, showing the feasibility of DAC applications in MS. Other isotopes with potential use for high pressure MS using DAC are suggested.
