On the reliability of intensity measurements for surface structure analysis by LEED

Abstract
The problem of the reliability of the experimental data in the structural investigations by LEED is studied by artificial enhancement of some of the major causes of error. In particular, the effect on the intensity spectra of the surface imperfections and of the instrument response function is investigated. The results indicate that in the energy range from 30 to 200 eV the spectra are only slightly affected, so that a high degree of reliability of the experimental data can be accepted.
