A comparison of desorption yields from C60⁺to atomic and polyatomic projectiles at keV energies Academic Article

abstract

• The desorption yields of negative ions from the impacts of keV energy C60+, (CsI)nCs+n=0, 1) and Ga+primary projectiles are compared. The experiments were performed in the event-by-event bombardment and detection mode using primary ion energies that ranged from 12 to 32 keV. Samples studied were vapor-deposited targets of CsI and phenylalanine. Compared at the the same energy, C60+produces 5 to 80 times higher secondary ion yields than Cs+or Ga+, primary ions commonly used in secondary ion mass spectrometry.
