| 英文摘要 | Convoy-electron emission has been investigated experimentally and theoretically for heavy-ion irradiation of conducting and insulating solid-state targets at a particle velocity of 14.1 a.u. (5 MeV/u). We present experimental evidence for a deceleration of convoy electrons produced by N7+, Ne10+, S13+, Ni23+ and Ag37+ ions during the interaction with insulator foils at normal incidence. The deceleration first increases with increasing projectile charge, reaches a maximum at a projectile charge of about 16 and seems to approach zero for even higher charges. It is proposed that there is a significant fraction of nuclear-track guided electrons emitted close to the convoy-electron velocity. The high ionization density inside the solid leads to an attractive potential that may guide electrons along the track, similar to the particle motion under channeling conditions.
