It has been usually assumed that under very general and common conditions the outcome of a collision experiment does not depend on the properties of the projectiles' beam [1]. However, recent evidence in ionization experiments [2] points to a breakdown of these conditions and a dependence of the collision outcome on the incident beam's coherence properties. These facts open the question of how is the result of a collision affected by the preparation of the projectiles' beam. This thesis presents a study of this problem analyzing inconsistencies of the standard stationary formulation of the scattering theory [1], and how these can affect the interpretation of projectile's coherence effects in ion impact collision experiments. To get this done, the framework of the De Broglie-Bohm formulation [3, 4] was used, which has recently recovered its lost mommentum due to its ability to deal with novel weak measurement results [5, 6]. In addition, this formulation is an advantageous option to describe a number of physical problems of current interest, such as the method of quantum trajectories developed by Robert E. Wyatt [7], or the study of effects such as the appearance of vortices in multichannel processes [8].
