“…The first and easiest comparisons between experiment and one-electron band theory dealt largely with Fermi-surface-sensitive probes, testing only the calculated states at the Fermi surface. Some of these results have been discussed by Switendick (11) and Cotts (1.2) • A lar,ge amount of work was carried out on the Pd-H system using a variety of theoretical (13,14,15,16) and experimental (17,18,19) techniques. Papaconstantopoulos and colleagues obtained agreement·with experiment when they showed that their calculated density of states versus H/Pd ratio varied in accordance with T as expected using the McMillan formalism (15).…”
