LXXIX. Energy band shapes and band widths in metals

摘要: Abstract The density of states curve given by the recent theory Bohm and Pines is compared with those Sommerfeld Hartree-Fock theories. It found that shows a rudimentary ‘tail’, effect this on interpretation experimental soft x-ray emission data discussed, particular reference to metals sodium, magnesium aluminium. Although band width great improvement theory, it still much larger than observed width. suggested may be partly due neglect short-range correlation energy: lower bound narrowing from cause calculated, 0·1 ev for sodium.
