Abstract

Rapid dissipation of energy is a prerequisite common to most of the modern techniques of ion formation from organic solids. With the particle impact methods like SIMS and fast atom bombardment (FAB) on the one hand and fission-fragment induced desorption (FFID), or more generally with respect to the type of primary ion, fast heavy ion-induced desorption (HIID) on the other hand, energy is brought into the lattice very rapidly either directly by collision cascades or via electronic excitation and subsequent polaron interaction. By means of Q-switched laser pulses electronic excitation takes place causing a rapid heating of the lattice, too. As a consequence, prompt ion formation from the surface occurs. Neither ion formation rates nor ion-to-neutral ratios, neither secondary ion type distributions nor primary ion/laser parameter dependencies are compatible with any quasiequilibrium processes [1]. It is assumed that these phenomena are to be treated in terms of a non-equilibrium surface-gas phase transition theory.
