In-beam Mössbauer Spectroscopy Using a Quantum Beam

Abstract

In-beam Mössbauer spectroscopy(IBMS) involves online measurement of Mössbauer γ-radiation emitted from excited atoms produced by radioisotope(RI) implantation and nuclear reactions. It provides us useful information on local atomic and electronic configurations, site distributions, dynamic diffusion processes, and unusual chemical states of isolated Fe atoms during the lifetime of the excited Mössbauer state. In this paper, the features and several application studies of the in-beam Mössbauer spectroscopy using a short-lived ⁵⁷Mn(T_1/2＝85s) are mainly mentioned.
