PROBLEMS
5.1. Consider a 200 nm free-standing film of Pt with 2 MeV 4He at nor-
mal incidence and the backscattering detector located at e, = 10°. .
For the backside of Pt at t = 200 nm, determine the following: (a)
the value of Ej, (b) the value of AEin (c) the value of E,, (d) the value
of AEs, (e) AEout, and (f) the value of AE. Hint: Use the surface and
mean energy approximations,​
