Interaction of Charged Particles with Matter
Recall diagram 5.3, p.84.
The crucial equation is for DE(b), the energy imparted to the light particle: DE(b) = z2r02m0c4M/(b2E)where E is the kinetic energy of the moving particle = (1/2)Mv2.
Thus it increases with decreasing impact parameter b
Energy imparted is inversely proportional to the kinetic energy E of the incoming heavy particle!
