Theoretically, the measured spacing between maxima or minima should increase linearly, due to the additional acceleration of electrons over the mean free path. If the electron beam has been accelerated to a potential that is equal to the discrete energy of the first excited level of Neon, inelastic collisions will occur. However, an electron must be close to a Neon atom in order for a collision to take place. The average distance that the electrons moves before the collision is known as the mean free path, $\lambda$. The electrons continue to gain energy over $\lambda$. If $\delta_{n}$ represents the energy gained by an electron over the mean free path, for $n$ inelastic collisions, the energy gained is:\\  \begin{equation}  \label{E_{n}}  E_{n}=n(E_{a}+\delta_{n})  \end{equation}  Given this equation the spacing between two minima or maxima should be given by:\\  \begin{equation}  \label{Equation} \Delta E_n = E_n - E_{n-1} = [1+ \frac{\lambda}{L} {(2n-1)}] E_a  \end{equation}  This equation is just of the form $\Delta E_{n}=A E_{a}$, where A is the constant, $A=[1+ \frac{\lambda}{L} {(2n-1)}]$. Thus the relationship between $\Delta E_{n}$ and $E_{a}$ is proportional, and the equation is linear.\\
