Scattering Cross Sections

Electron penetration in semi-infinite Au for normal and oblique angles of incidence at energies between 0.5 and 4 keV is simulated within a Monte-Carlo frame work. The elastic scattering cross sections have been obtained from a modified Rutherford differential cross section, whereas inelastic core and valence electron excitation are calculated using the Gryzinski's expression. The dependence of the backscattering coefficient, mean implantation depth and stopping profiles on the angle of incidence has been examined. These quantities are found to be significantly enhanced as the angle of incidence becomes higher which is generally in consistent with previous simulations.

Two Temperatures

The absolute photoabsorption cross sections of [Formula: see text] and [Formula: see text] have been measured at two temperatures (evaporative ensemble, 115 K). The maximum of the observed resonance is nearly independent of the temperature and agrees within 5% with the Mie plasmon resonance as calculated from the bulk electron density of cesium. This is in contrast to the sodium case, where the plasmon is redshifted by about 20%. For n=9 and 21 the integrated oscillator strength amounts to 89% [Formula: see text] and 73% [Formula: see text] per valence electron in the energy range 1.5 eV<hν<3.0 eV.
