電子回折研究の誕生期―電子回折発見50年祭の年に当って―

抄録

A historical review is given of the discovery of electron diffraction as well as the succeeding development of electron diffraction studes. Efforts and struggles of early pioneers, both in abroad and in Japan, are described in some detail. It is pointed out that Japan's main contribution in the field of electron diffraction following Kikuchi's work of the cathoderay diffraction by mica crystals is characterized by efforts concentrated on“the electron diffraction physics”, in particular those related to the dynamical diffraction process and inelastic scattering. In this connection, discussions are given of a series of simple but typical examples of multi-wave problems that are related to some recent topics such as the critical-voltage effect. Also, reminiscence of Prof. Miyake's own works is presented, in which the main features of the phenomenon of surface-wave excitation are outlined.
