This is called bragg peak, after william henry bragg who discovered it in 1903. When xrays are incident on an atom, they make the electronic cloud move, as does any electromagnetic wave. In fact, the ionization density follows closely the let. With slowing, the let at first continues to increase because of the strong velocity denominator in the kinematic.
