摘要: The dielectric constant of potassium is determined from 2.07 eV to 6.2 by using only s -polarized light. e 1 -spectrum expressed 1.23-(λ/2920) 2 in λ 3600A. - and -spectra are compared with the other published data, discussed sum rule dispersion relation. loss function separated absorption spectrum for p light, calculated constant. two functions seem be different half width.
