Differential cross sections for the elastic scattering of electrons by neon

Comparison of an Electron−Atom-Scattering Description with Gas-Phase Scattering Data for He, Ne, Ar, Kr, and Xe

“…The elastic scattering processes were deconvoluted from the other processes by taking advantage of the absence of geometric structure in gas-phase electron−atom-scattering experiments. The elastic portion of the description was tested in the 50−1000 eV KE range using published electron-scattering data for the rare gases. − Excellent agreement with experiment is found. Relatively few parameters are required and each parameter represents a specific property of electron scattering.…”

“…Gas-phase electron-scattering data, such as definitive results which have been reported for the rare gases (He, Ne, Ar, Kr, and Xe), are important to the development of an accurate description of Auger electron scattering in the solid state because such data allow the scattering behavior which results from single electron−atom interactions to be examined. Particularly useful are the measured values of the elastic differential scattering cross sections (intensity distribution vs scattering angle) − and the total cross sections: − Scattering cross sections are more easily obtained from low pressure gas-phase data than from solid state data because gas-phase measurements are relatively uncomplicated by multiple scattering . Also, structure considerations are negligible for gaseous samples, such that cross section measurements allow the relative probabilities of elastic and inelastic scattering processes to be evaluated, leading to a quantitative description which conserves electrons: For example, gas-phase scattering data for Xe show that inelastic scattering processes contribute about 72% of the total scattering cross section at KE = 350 eV 45-49 while diffuse elastic scattering and diffraction processes account for the remaining 28%.…”

Scattering of e ± from the neon isonuclear series over the energy range 1 eV–0.5 GeV

“…[7][8][9] The literature is rife with experimental studies on the scattering of electron by neon atom. DCSs for electron scattering have been measured by Gulley et al 10) (0.75-7 eV); Brewer et al 11) (7.5-20 eV); Register and Trajmar et al 12) (5-100 eV); Williams and Crowe 13) (20-200 eV); Bromberg 14) (200-700 eV); DuBois and Rudd 15) (50-800 eV); Gupta and Rees 16) (100-625 eV) and Jansen et al 17) (100-3000 eV). DCSs for positron scattering at few energies have been reported by Kauppila et al 18) Knight et al 19) and Kauppila et al 18) measured the energy variation of DCS for electron scattering and positron scattering respectively.…”

Density Variation in Heat- and Pressure-Treated Egg White during Gel-to-Glass-like Transition

“…We used the same data as Naccache and McDowell (1974) except for the total cross section above 20 eV. where we took the values recommended by de Heer and Jansen, while we also include the differential cross sections of Gupta and Rees (1975) at 100 eV. We find a better fit to the diffusion cross section data, which are probably more accurate below 7 eV than any of the other measurements, by supposing that the total elastic cross sections fall slowly from the Andrick and Bitsch curve at 7 eV to Golden and Bandel's value at 1 eV.…”
