在低温（T0=24.7 K）自由射流膨胀1%H_2和99%4He气体产生的分子束中发现了HeH_2货车范德华络合物。光束中弱结合的HeH2络合物通过100 nm周期透射光栅后通过其一级衍射角识别。的衍射图案的电子碰撞质谱仪分析用于歧视的组成气体团簇的离子碎片。
The HeH2 van der Waals complex has been identified in a molecular beam produced by a cryogenic (T0=24.7 K) free jet expansion of a 1% H2 mixture in 99% 4He gas. The weakly bound HeH2 complexes in the beam are identified via their first order diffraction angles after passing through a 100 nm period transmission grating. An electron impact mass spectrometer analysis of the diffraction patterns is used to discriminate against ion fragments of the constituent gas clusters.
