On the other hand, if the line of incidence of the α-particle is a distance b, from the nucleus (b is called the “impact parameter”), thenthe scattering angle will be smaller. 2.1 Relation between scattering angleand an impact. parameter.

Answer:
Explanation:
A simple and general expression for the classical scattering angle in binary collisions of particles in fields of arbitrary potential is derived. The relationship is very convenient for interpretation of scattering experiments and for theoretical studies of three-dimensional repulsive collisions because it allows one to express the amount of energy and linear momentum transferred between the colliding particles as a simple function either of the collision impact parameter or of the scattering angle.
