摘要：
Metastable helium molecules produced in electron bombarded helium nanodroplets subsequently are detached by infrared radiation. Electron emission when the detached metastable molecules strike surrounding surfaces permits highly sensitive detection of the absorption spectrum. Recent experiments utilize a new tunable infrared laser source and permit much higher resolution measurements than previously obtained. The rotational structure is clearly resolved and sharply structured as a result of the molecule-surface interaction. (C) 2000 Elsevier Science B.V. All rights reserved.
