摘要：

Electron stimulated desorption of O- ions has been demonstrated from the CO/W system. Ion yields are shown to be approximately a factor of 50 smaller for O- than for O+. The O- species is shown to originate from both α-CO adsorption states with an estimated 80% of the O- signal coming from the CO+ producing α-state. Preliminary results indicate that the ion energy distribution for O- is broader and peaks at a higher energy than for the O+ ions. © 1979.
