Question

4. The inelastic mean free path of electrons in a solid determines the surface sensitivity of the photoelectron spectra, and depends on the kinetic energy of the electrons. For an electron with an inelastic mean free path $\lambda$ of 30\AA, calculate the fraction of photoelectrons which get inelastically scattered if they are emitted at a depth of 50\AA from the surface. What is the fraction scattered inelastically, if the depth is 250\AA?
