We demonstrate that a standard approximation in the integration conditions of the transferred momentum, which isfrequently employed for the study of the interaction of charged projectiles with condensed matter, might lead to inconsistentresults. We propose a method for avoiding these shortcomings. Finally we exemplify this issue by studying the excitation ofbulk plasmons by a particle penetrating a semi-infinite material at an oblique trajectory.
