摘要：
The nonlinear effects in sputtering under atomic and molecular ion bombardment are considered taking into account the straggling of primary ion energy deposition near the solid surface. Such consideration is necessary when the mean value of stopping power is not sufficient for a treatment of the spike effects. It is shown that the sputtering yield from a spike region, especially in the case of low energy deposition is not determined by the energy loss alone. The results of the calculations are compared with the experimental data on sputtering of solids under molecule bombardment.
