Using the root mean square speed, Vms = | v?|12= V(3kT/m), calculate the gas temperatures of He and Ar for which A = 0.2 nm, a typical value needed to resolve the diffraction from the surface of a metal crystal. On the basis of your result, explain why Ar atomic beams are not suitable for atomic diffraction experiments.
