Abstract

An analysis is performed of the mass spectrum of resonance electron capture by tetracyanoquinodimethane molecules, in which long-lived negative molecular ions are detected. At 3.6 eV, the ions can be attributed to an electron-excited Feshbach resonance with an admixture of a long-lived ground state whose contribution to the superposition of two states yields a measurable ion lifetime in the microsecond range.

摘要

对四氰基喹二甲烷分子捕获共振电子的质谱进行了分析，其中检测到了长寿命的负分子离子。在3.6 eV时，离子可以归因于电子激发的Feshbach共振，以及长寿命基态的混合物，该基态对两种状态的叠加产生可测量的离子寿命，范围为微秒。
