Differential Cross Section of Electron Scattering from Molecular Hydrogen. II. b³Σ_u⁺Excitation

Amplitude and phase components of the nonlinear response of dyes

“…Discrepancies of the same magnitude are also seen in the forward and in the backward direction for 20eV impact electrons. Comparing the results of both theories with experimental data (Hall and AndriC 1984, Nishimura and Danjo 1986, Khakoo et a1 1987, there is a quite satisfactory agreement for the incident energies studied herein, especially if the substantial differences between those data, as reported in the literature, are considered. Figures 4-6 show the DCS for the excitation X 'E; + a ' C l .…”

“…Firstly, there is a lack of systematic experimental results in the literature. The available experimental cross sections are quite fragmentary (Trajmar et a1 1983) and sometimes show significant discrepancies (Khakoo et a1 1987, Nishimura and Danjo 1986, Hall and AndriC 1984 between themselves. In addition, there are very few theoretical studies beyond the DWA level (Chung and Lin 1978, Holley et a1 1982, Weatherford 1980, Lima et a1 1985, Schneider and Collins 1985, Baluja et al 1985 in the literature.…”

“…Same as infigure 1for 20 eV. The experimental data are: full squares,Nishimura and Danjo (1986); full circles, Khakoo er a / (1987).…”

Structure of the Set of Sums of a Conditionally Convergent Series in a Normed Space

“…Much of the more recent experimental effort has concentrated on measuring nonresonant differential and total cross sections for the various electronic excitation processes (Watson and Anderson 1977, Ajello et al 1982, Hall and Andric 1984, Pasquerault el a1 1985, Mason and Newell 1986b, Khakoo and Trajmar 1986, Nishimura and Danjo 1986, Khakoo et a1 1087. These measurements are difficult and, in particular, it is often not possible t o obt>ain reliable total cross sections; exactly the d a t a required when modelling astrophysical or plasma processes.…”

Estudo teórico do espalhamento elástico e inelástico de elétrons por moléculas de H2

“…Figura 7.1: Seção de choque diferencial para o espalhamento inelástico de elétrons por moléculas de H2 para a transição X l Eg + -> b'Eu + com energias do elétron incidente iguais a: (a) 15eV e (b) 18eV. Linha sólida, nossos resultados MCMCF a 5 canais; linha tracejada, nossos resultados MCMCF a 2 canais; linha tracejado pequeno, resultados de Parker et al [40]; quadrados, dados experimentais de Nishimura e Danjo [42]. [49]; triângulos, dados experimentais de Khakoo e Trajmar [41]; círculos abertos, dados experimentais de Hall e Andric [50].…”
