Total integral and ejectedenergy differential cross sections for the electronimpact ionization of lithium
Abstract
Timedependent closecoupling calculations of the electronimpact ionization of lithium are presented and compared to experiment and other recent theoretical calculations. Total integral cross sections are found to be in excellent agreement with the previous converged closecoupling calculations of Bray [J. Phys. B 28, L247 (1995)], but are substantially lower than the only lowenergy region experimental results of Zapesochnyi and Aleksakhin [Sov. Phys. JETP 28, 41 (1969)]. Ejectedenergy differential cross sections are presented for incident energies of 10 eV, 15 eV, 20 eV, and 25.4 eV. At 25.4 eV, the timedependent closecoupling results are found to be in only moderately good agreement with the converged closecoupling results of Bray et al. [J. Phys. B 32, 4309 (1999)]. A study is also made of the convergence of the spin asymmetry parameter as a function of orbital angular momentum. The final timedependent result for the spin asymmetry parameter at an incident energy of 15 eV is found to be in excellent agreement with the converged closecoupling results of Bray [J. Phys. B 28, L247 (1995)], but is slightly lower than the experiment of Baum et al. (1985).
