In this work, p+H (proton hydrogen) atom-ion collision is considered as a quantum
control objective through solving a quantum system described by time dependent
Schrodinger equation. For different internuclear distances, the colliding particles
are controlled via applying an appropriate intense laser field. It means that one
can control certain particle collision in the viewpoint of quantum mechanics at the
atomic scale. It is possible to achieve the quantum control of particular colliding
process theoretically and computationally, although the realization for poly-particles
collision are fairly inadequate. Furthermore, the enhanced ionization rate reaching
maximum at a critical internuclear distance is also surveyed together in this way.
