Hyperfine Interactions 13 (1983) 199-219 Experimental Techniques for Conversion Electron Mössbauer Spectroscopy J. A. Sawicki and B. D. Sawicka Conversion electron Mössbauer spectroscopy has grown during the last decade as a new tool of surface science. High sensitivity, depth selectivity and capabilities of the method in nondestructive backscattering analysis are essential features of CEMS. These virtues made the method advantageous in varoius applications and stimulated considerable progress in experimental techniques. The latter is the subject of the present paper.
