Analysis of the low-lying spectrum of the He-tetramer

doi:10.1088/1009-1963/11/3/310

Abstract

Abstract There is a type of nodal surface imposed by symmetry on wavefunctions. These surfaces are crucial to the ordering of low-lying states. Based on an analysis of this type of surface and based on existing theoretical results, the feature of the low-lying spectrum of the He-tetramer is studied, and the candidates of bound states and narrow resonances are suggested.

Keywords: He-tetramer atomic cluster effect of symmetry
