| Research Abstract |
We carried out a systematic study of the recoil effects of photoelectrons in solids, both experimentally and theoretically. Not only the core electrons in crystals such as C, Al, BN, MgB2, but also the nearly free electrons in the conduction band of Al showed the recoil effect. By a theoretical investigation, all of the experimental data have been analyzed successfully, and the importance of the recoil effects has been clarified.
