چکیده

We report the first direct measurement of the kinetic energy of exoelectrons produced by collisions of vibrationally excited molecules with a low work function metal surface exhibiting electron excitations of 64% (most probable) and 95% (maximum) of the initial vibrational energy. This remarkable efficiency for vibrational-to-electronic energy transfer is in good agreement with previous results suggesting the coupling of multiple vibrational quanta to a single electron.

Vibrationally promoted electron emission from low work-function metal surfaces.

We observe electron emission when vibrationally excited NO molecules with vibrational state v, in the range of 9 < or = v < or =18, are scattered from a Cs-dosed Au surface. The quantum efficiency increases strongly with v, increasing up to 10(-2) electrons per NO (v) collision, a value several orders of magnitude larger than that observed in experiments with similar molecules in the ground vib...

Inverse velocity dependence of vibrationally promoted electron emission from a metal surface.

All previous experimental and theoretical studies of molecular interactions at metal surfaces show that electronically nonadiabatic influences increase with molecular velocity. We report the observation of a nonadiabatic electronic effect that follows the opposite trend: The probability of electron emission from a low-work function surface--Au(111) capped by half a monolayer of Cs--increases as...

Vibrationally promoted emission of electrons from low work function surfaces: Oxygen and Cs surface coverage dependence

We observe electron emission from low work function Cs covered Au surfaces due to the scattering of vibrationally excited NO molecules with 18 quanta of vibration in the ground electronic state. Additional experiments explore the influence of oxygen exposure on the electron emission. These results indicate a nondissociative mechanism for reactivity of vibrationally excited NO on these surfaces ...

Vibrational enhancement of electron emission in CO (a3Π) 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, γ, of CO (a(3)Π) 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.

Ion-induced electron emission from MgO by exciton decay into vacuum

We report observations of electron emission from MgO surfaces induced by impact of 100 eV–4 keV He, Na, Ne, Ar ions. The energy distribution of emitted electrons is nearly independent of ion type and energy, showing that it is caused by the decay of an intrinsic electronic state of the solid excited by the ions. The similar yields and energy distributions for incident Na and Ne ions rule out th...
