Homework Statement
1. Let -Q charge be uniformly distributed over a sphere radius R. Find f(|\vec{G}|), the atomic form factor.
2. Let the incident xrays have wavelength \lambda, determine the dependence of f(|\vec{G}|) on \theta, the scattering angle.

Exactly, since quantum statistics becomes Boltzmann maxwell statistics at the classical limit, so I have the +/- for generality. Thus, regardless of a BE or FD distribution, taking the classical limit will give back classical stat.
Now, the question is, do I use classical statmech or quantum...
Consider an ideal gas of oxygen atoms in equilibrium with oxygen atoms absorbed on a planar surface. here are N_s sites per unit surface area at which the atoms can be absorbed, and the energy of an absorbed atom is -e compared to one in the free state. The system is under 1 atm and at 300K...
