Then, as a result of spherical scattering, the outgoing wave will be given by the sum of the plane and the spherical waves. 1 Conservation Laws in Collisions First we assume that the collision event occurs in a force-free space, in which the momentum and energy of the two particles are conserved. This is true, for example, for an electron collision with a neutral molecule, which is the most frequent type of collision occurring in collisional plasmas, where the interaction time between the two particles is on the order of 10−16 s, and the effect of the external force due to an imposed electric field is negligible compared with the huge internal force between the two particles.

We now introduce the impact parameter b to the binary collision with b representing the perpendicular distance from the z-axis along the initial relative velocity to the center of the target. 5) that only those particles with an impact parameter b less than a 1 + a 2 will collide, whereas others will continue their motion without changing their direction. Thus the circle with radius a 0 = a 1 + a 2 is the effective size of the target for projectiles represented as points. The area of this circle πa 02 = π(a 1 + a 2 )2 is the effective collision cross section for the two hard spheres.

R = const. 1 Classical and quantum (plane wave) description of a particle with the mass m and momentum p(0, 0, pz ). The energy of a particle is equal to the potential drop V0 times the elementary charge e, so we can obtain the momentum of the particle as a function of V0 : ε = p 2 /2m = eV0 . 3, we obtain p = h¯ k = h 2π h = . 50 V0 [V] 1/2 [nm]. 2 A stationary electron beam with mono-energetic energy eV0 produced in a vacuum. 4). 4 gives us h¯ 2 k 2 (r, t) = h¯ ω (r, t). 2m Finally, we obtain the dispersion relation (between the wave number k and the angular frequency ω) ω(k) = h¯ k 2 .
