摘要：

A technique in which the H(2s) metastable population of a fast hydrogen atom beam is modulated by electric field quenching has been used to study the collisional de-excitation of 5-26 keV H(2s) atoms in passage through H 2, He, Ne, Ar and Kr. Cross sections sigma 2s.2p for 2s-1s de-excitation via the 2p state have been determined for the first time and shown to account for no more than about 15% of the total cross section for de-excitation. Checks have been made on the authors' previously measured total cross sections for one-electron loss by H(2s) atoms.
