Jb. Boffard et al., Use of a fast beam target for the determination and reduction of the cascade contribution to electron excitation cross-section measurements, EUR PHY J D, 8(2), 2000, pp. 193-198
This paper describes a method for reducing the influence of cascades on the
measurement of electron excitation cross sections using the optical method
and a fast beam atomic target. By using a fast beam of target atoms one ca
n reduce the influence of cascades on a measurement, and estimate the casca
de contribution to the excitation signal.
