摘要：
The register line formalism of angle-resolved photoemission is applied to the special case where electrons are excited from sp surface states. By considering lifetime broadening alone, it is demonstrated that it is possible to explain why photoemission linewidths increase as the initial states disperse towards the Fermi level. Favourable comparisons are made between the theory and with measurements of the surface state widths on Cu(111) and Al(001).
