Calculation of electron-impact rotationally elastic total cross sections for NH3, H2S, and PHLimbachiya1, Vinodkumar2, Mason3 2011Phys. Rev. A363180View full textAdd to dashboardCite

“…The total elastic cross sections including electronic excitations are computed and plotted below the ionization threshold with total cross sections obtained as the sum of elastic and inelastic cross sections plotted above ionization threshold. The present results are in fairly good agreement with the experimental data of Jones et al [5], Bruche [7], Zecca et al [9], Garcia et al [11], and Ariyasinghe et al [12]. In particular the present results are in very good agreement with the experimental results of Sueoka et al [10] below 4 eV and above 100 eV, between 4 and 10 eV the present data are slightly lower than results of Sueoka et al [10], while above 15 eV the present results are slightly higher.…”

“…The experimental data of Szmytkowski et al [6] are in good agreement with present results throughout the range except near the peak, where they are higher compared with other reported values. The experimental data of Alle et al [8], produced by extrapolation and integration of the differential [9]; stars, experimental data of Sueoka et al [10]; crosses, experimental data of Garcia et al [11]; diamond (filled), experimental data of Ariyasinghe et al [12]; inverted triangles, experimental data of Szmytkowski et al [6]; filled circles, experimental data of Alle et al [8]; open squares, experimental data of Bruche [7] ; open circles, experimental data of Jones et al [5].…”

Analytic Cross Sections for Electron Collisions With Co, Co2, and H2o Relevant to Edge Plasma Impurities

“…Measurements of the total scattering cross section (Graph 70) have been reported by Brüche [57], Sueoka et al [58], Szmytkowski [59], Zecca et al [60], and T. SHIRAI, T. TABATA, and H. TAWARA e − + CO, CO 2 , and H 2 O Nishimura and Yano [61]. A recent remeasurement was carried out by Saǧlam and Aktekin [62] with uncertainties ranging from ±1.3 to ±8.3% in the incident energy range 4-20 eV using an attenuation method.…”

Positronium- and positron–H2O total cross sections

“…Electron collisions with water molecules have been studied for many years (see e.g. recent review by Itikawa and Mason (2005)), with total cross sections (σ T ) being reported since 1929 (Brüche 1929, Sokolov and Sokolov 1986, Sueoka et al 1986, Szmytkowski 1987, Zecca et al 1987, Jain 1988, Nishimura and Yano 1988, Saglam and Aktekin 1990, 1991. Convergence among recent measurements of σ T is found at high energies whilst uncertainties remain at low energies.…”
