Impact Parameter, Scattering Angle, and Distance of Closest Approach

1 Impact Parameter, Scattering Angle, and Distance of Closest Approach [Pg.92]

The distance of closest approach or collision diameter d of the incoming particle, for head-on collision with the target nucleus is given by [Pg.92]

For backscattering to occur, the projectile and target must get close enough together such that the distance of closest approach is within the K-shell radius, and that is why we can ignore the electrons. [Pg.93]
