在本文中，我们证明了原子间库仑衰变（ICD）是自由Ne簇中Ne 2s内价空位的主要弛豫通道，其效率接近100%。ICD是指弱键原子或分子簇中空位的一种新的自电离过程。它的主要特点是一个电子从不同于原来空位的位置释放出来，这是由超快能量转移介导的。结果显示在大约。50 - 600原子。对于较大的团簇，效率明显提高的趋势可能是由于团簇内部的非弹性散射过程。(c) 2006 Elsevier B.V.版权所有
In this article, we demonstrate that Interatomic Coulombic Decay (ICD) is the dominant relaxation channel of Ne 2s inner valence vacancies in free Ne clusters, with an efficiency close to 100%. ICD designates a novel autoionization process of a vacancy in a weakly bonded atomic or molecular cluster. Its main characteristic is the release of an electron from a site different than the original vacancy, which is mediated by ultrafast energy transfer. Results are shown for cluster sizes between approx. 50-600 atoms. A trend towards apparently increased efficiency for larger clusters may result from inelastic scattering processes inside the cluster. (c) 2006 Elsevier B.V. All rights reserved.
