Abstract

Helium droplets represent a cold inert matrix, free of walls with outstanding properties to grow complexes and clusters at conditions that are perfect to simulate cold and dense regions of the interstellar medium. At sub-Kelvin temperatures, barrierless reactions triggered by radicals or ions have been observed and studied by optical spectroscopy and mass spectrometry. The present review summarizes developments of experimental techniques and methods and recent results they enabled.

摘要

氦滴代表一种冷的惰性基质，没有壁面，具有在完美模拟星际介质冷而致密区域的条件下生长复合物和团簇的卓越特性。在低于开尔文温度下，通过自由基或离子引发的无势垒反应已通过光谱学和质谱法进行了观测和研究。本综述总结了实验技术和方法的发展以及它们所取得的最新成果。
