Is there anybody can help me to solve this question:
A sphere of radius=R0 has gas in it;
There has a potential V(R)=V0*exp[-(R-R0)/a].
The atoms are colliding in the sphere, and the potential acts on the particles.
The question is:
How to get the Fourier transform of V(t), i.e.
Integral(from -inf to +inf) [V(t)*V(t+tau)]*exp(-i omega t) d tau
you may consider potential is much smaller than the kinematic energy, if otherwise too difficult to solve.
Thank you!
