Сollision of a point particle and an infinitely thin planar domain wall interacting gravitationally within linearized gravity in Minkowski space-time of arbitrary dimension is investigated. We describe analytically perforation of the wall by the particle, showing that it is accompanied by excitation of the spherical branon shock wave propagating outwards with the speed of light. Since the metric of the wall increases with distance, the wall and the particle are never free, so the energy-momentum balance under collision is non-trivial. We show that contribution of the gravitational stresses effectively localizes on the particle and the wall world-volumes giving the possibility to introduce relativistic potential energies of each object in the gravitational field of the partner.
