How large is the collision cross section compared to nuclear fusion cross section

How do we calculate the minimum time the particles are supposed to stay close enough for fusion to occur?

Another Question, I've been reading about cross sections and then I kind of got confused. What exactly is the difference between elastic scattering cross section, Differential cross section, Rutherford scattering cross section and coulomb collision cross section? Aren't these all elastic? Than why do we have so many terms? I don't understand the difference.

Please keep the cross section questions in your other thread about cross sections. Multiple parallel threads about the same topic don't help.
