Status of conversion electron mössbauer spectroscopy in ion implantation studies

Abstract

In this paper, some new developments in conversion electron Mössbauer spectroscopy (CEMS) and its recent applications in the study of ion-implanted materials are presented. On-beam CEMS measurements are now possible at temperatures from 4 to 1200 K in ultrahigh vacuum. The range of applications of the 57Fe resonance is rapidly expanding and experiments with 119Sn, 151Eu and 197Au have recently been initiated. A brief survey of current research subjects is presented; this includes local packing and charge transfer effects in iron-implanted alloys, formation of multiple charge states and annealing effects in inorganic insulators, light ion implantation effects in steels, ion beam mixing effects and applications in materials studies for thermonuclear fusion.
