Electron State in BeO Studied by Compton Scattering Measurement

Abstract

In order to investigate the electron state in BeO, the Compton profile has been measured on a powder sample by use of AgKα radiation. On the other hand, theoretical profiles have been calculated from available four sets of electron wave functions, which mostly concern isolated atoms. Comparison of the observed profile with the theoretical ones showed that wave functions of Be ++ O - state are better than those of BeO and Be + O - . However, there still remains small discrepancy, which may be due to complexity of chemical bond in solid state. In the appendix, a numerical table is given for the theoretical Compton profiles due to atoms, Be + , Be ++ , O - and O - , which have not so far been published.
