Abstract

Abstract The role of the number of basic vectors in the calculation of angle-resolved photoemission spectra from the (110) surface of a fcc metal has been studied. It is found that one should use at least 45 basic vectors to enquire convergenced intensities in calculations. The same kind of spectra are also obtained by using 15 or 31 basic vectors. Tentative explanation for this is given. Comparison between experimental and theoretical spectra of Pd(110) is presented.
