Electron-impact excitation of krypton
Physical Review A, 1985First-order many-body theory has been used to calculate the differential, integrated, and momentum-transfer cross sections for the electron-impact excitation of the 5s'((1/2))/sub 1//sup 0/( /sup 1/P/sub 1/ ), 5s((3/2))/sub 1//sup 0/( /sup 3/P/sub 1/), 5s'((1/2))/sub 0//sup 0/( /sup 3/P/sub 0/), and 5s((3/2))/sub 2//sup 0/( /sup 3/P/sub 2/)= states of ...

Excitation of Be+ by electron impact
Journal of Applied Physics, 1983A realistic analytic central potential is used to generate wave functions for the ground and excited states of singly-ionized beryllium. Generalized oscillator strengths and integrated cross sections from threshold to 5 keV are calculated in the Born approximation for 2s-ns, 2s-np and 2s-nd excitations.

Double Excitation of Helium by Electronic Impact
Physical Review Letters, 1963The cross section for electron impact excitation of He to the doubly excited (2p)/sup 2/ /sup 3/P/sub 3/ state was calculated. This state is the lowest lying, doubly excited state that is stable to autoionization. The differential cross sectlon results indicate that the scattered beam has an intensity maximunm at right angles to the incident beam.

The Double Excitation of Helium by Electron Impact
Mathematical Proceedings of the Cambridge Philosophical Society, 1935The probability of excitation of helium by electron impact to the more important doubly excited levels is calculated, and comparison made with the experimental results of Priestley and Whiddington who have observed two lines due to double excitation. The calculated relative intensities and angular distributions are found to be in qualitative agreement ...

The case study part of this book begins in Sect. 7.1 with the presentation of a few examples where either unpolarized or spin-polarized electron beams are used to excite unpolarized atoms. Only the emitted light and its polarization, but not the scattered electrons, are observed.

Electron-impact excitation of oxygenlike krypton
Physical Review A, 1986Electron-impact excitation cross sections have been calculated for transitions from the ground state 2s/sup 2/2p/sup 4/ /sup 3/P to the n = 2 and n = 3 excited states of oxygenlike krypton. Configuration-interaction-type wave functions were employed, and the cross sections were calculated in a close-coupling approximation for impact energies ranging ...

Electron-impact excitation of atomic copper
Physical Review A, 1986Cross sections are calculated for excitation of Cu for elastic scattering of electrons from the 4s ground state and for excitation to excited states 3d/sup 9/4s/sup 2/, 4p, and 4d. A three-state close-coupling approximation is used for the energy range 3.8 < E < 10 eV, and a four-state one for 6 < E < 100 eV.

Electron-impact excitation of molecular ions
Physical Review A, 1989A simple expression is derived that relates the rate coefficient for dipole-allowed electron-impact excitation of a molecular ion in the Coulomb-Born approximation to the Einstein /ital A/ coefficient for the corresponding radiative decay. Results are given for several molecular ions of astrophysical interest.

Publisher Summary This chapter describes some general programs developed to investigate collisions of electrons with atoms and ions of arbitrary complexity in LS-coupling. The integro-differential equations are converted to a set of linear algebraic ones and the program is called IMPACT.
