The dynamics of resonant charge transfer in hyperthermal energy ion-surface collisions

I have studied the dynamics of resonant charge transfer in hyperthermal energy collisions of positively charged alkali ions with clean and alkali-covered Cu(001) surfaces. Li;I have studied the dynamics of charge transfer by measuring the work function dependence of the absolute yields of different charge states and of the relative yields of excited states in the scattered flux that results when hyperthermal energy Li...
