Abstract :

Calculation and further analysis of density matrix (DM) for projectile which collides with a solid film reveals some new representations which is hard to be anticipated without the calculation namely: The coherence properties in the projectile�s wave field are describing through the special function of coherence. The collision with the solid leads to a significant decrease in the total coherence length of the projectile�s wave field. The coherence length can become much smaller than the initial size of a wave packet of a particle passing through the film. During the collision with solid the number of different spatial areas where the mutual coherence in the projectile�s wave field is supported, can be multiplied. Every part of projectile�s wave field can be individualizing as the separate particle having own property in its inner quantum state. The procedure which has a responsibility for such a transformation can be characterized as a spontaneous breaking of symmetry. The process described in the point 3 can be considered as a special form of breaking in quantum mechanics. Knowing the wave packet evolution during the passage through the solid film allows one to explain experimental results on the pore formation during the passage of high charged atomic ions through the thin carbon nanomembranes. The parts of the wave field considered above can be stabilized in its quantum state after it has been captured in its own polarization well.
