Vibrational enhancement of electron emission in CO (a super(3) capital pi ) quenching at a clean metal surface

Vibrational enhancement of electron emission in CO (a super(3) capital pi ) quenching at a clean metal surface

We have combined a Stark decelerator with a molecular beam-surface scattering setup to accurately measure the absolute electron emission yield, gamma , of CO (a super(3) capital pi ) quenching at a Au(111) surface with quantum state resolution. We clearly observe an enhanced probability of electron...

Zusammenfassung:We have combined a Stark decelerator with a molecular beam-surface scattering setup to accurately measure the absolute electron emission yield, gamma , of CO (a super(3) capital pi ) quenching at a Au(111) surface with quantum state resolution. We clearly observe an enhanced probability of electron emission when scattering vibrationally excited states of CO from the surface.
