Abstract
The authors performed optical measurements consisting of near normal incidence reflectance (2-11 eV) and multiangle reflectance measurements (11-15 eV) on gallium films condensed on cooled glass substrates in a vacuum of 2*10-10 Torr. Optical constants were determined with the help of a Kramers-Kronig analysis of the reflectance data. The optical conductivity sigma , real part of the dielectric constant epsilon 1 and energy loss function -Im(1/ epsilon ) were deduced. epsilon 1 against 1/(h(cross) omega )2 shows a linear dependence; -Im(1/ epsilon ) peaks at (14.05+or-0.05) eV.Keywords
