摘要：

The time-dependent close-coupling theory is applied to the study of the electron-impact ionization of helium from the excited.(1s2s) configuration. Calculations are made-in,an effort to resolve the discrepancy between theoretical calculations and existing experimental measurements for this cross section. We find good agreement with the existing convergent close-coupling calculations of Bray and Fursa [J. Phys. B 28, L197 (1995)], but are in substantial disagreement with the experimental measurements of this quantity by Dixon et al. [J. Phys. B 9, 2617 (1976)].
