氢分子团簇的实验和理论研究

氢分子是宇宙中结构最简单的分子，而它的团簇是分子团簇科学的研究模型。目前，氢分子团簇的结构和动力学仍是基础科学研究的热点之一。氢分子团簇的实验和理论研究主要集中在三个方面：团簇的形成条件和尺度分布；团簇的电离能和出现势；以及氢分子团簇的量子化学计算研究等。我们主要介绍了国外氢分子团簇实验和理论研究的现状，同时也对我们在氢团簇的光电离研究方面取得的进展进行了介绍，希望能为以后氢分子团簇的基础和应用研究提供一些参考信息。

Experimental and theoretical study of hydrogen clusters

The structure of hydrogen molecule is the simplest in the universe, while its neutral cluster is a research prototype of molecular cluster science. At present, the study on the structures and dynamics of hydrogen clusters is still one of keystones in the research of basic sciences. Meanwhile, emphases of experimental and theoretical studies of hydrogen clusters are focused on the following three aspects: formation conditions and size distribution, ionization energy or appearance energy, and studies of quantum chemistry. The present status on the experimental and theoretical studies of hydrogen clusters are introduced here mainly. At the same time, the research progress of the photoionization of hydrogen clusters accomplished in our group are also introduced. We hope some information is provided for the research of basic and application of hydrogen clusters in the future.
