摘要
We report on (e, 2e) experiments for excitation-ionization of helium made in asymmetric geometry at intermediate incident energy and low momentum transfer. The results are compared with Born 1 calculations. Some degree of agreement is obtained and seems to be improved by correction for post-collision interactions. But it cannot be expected that such simple models will correctly reproduce processes that depend so strongly on correlations.
