| Research Abstract |
Vicinage effect on secondary-electron (SE) emissions from a solid induced by bombardment with molecular/cluster ions having faster velocity than the Bohr velocity is one of the open questions in the physics of ion-solid interaction. In this study, we demonstrate that the vicinage effect on SE emissions consists of two contributions: one originates from the production process of scattered electrons, the other originates from the transport process of the scattered electrons, and the dominant contribution depends on an internuclear distance between the dissociated ions.
