Abstract
Fast heavy ions have been used to desorb and ionize biomolecules, like small proteins, from a solid sample surface. Mass spectra were studied by the time-of-flight method. A model for the desorption process, based on the ion-track concept, has been developed and used to analyze yields of molecular ions as a function of the energy density in the ion track. Experimental data on the yield dependence of sample thickness are presented.
