Scattering in a central potential

[Logarythmic]

How can I compute the differential scattering cross section $$\sigma (\theta) d \theta$$ for scattering in the central potential
$$V(r) = \frac{k}{r^2}$$
using classical mechanics?

Ever seen Rutherford's approach to alpha particles scattered on a Coulomb potential made by the gold atoms ?

Just mimick the computations.

If you mean the Geiger-Marsden experiment, I have read about it but never seen any calculations. Any tip on where I can find it?

Appendix #9 from Max Born's "Atomic Physics" is the first i could come up with.

Well, that book is not a part of my collection so can you help me in any other way? ;)

Google for it. Here http://www.du.edu/~jcalvert/phys/ruther.htm

Sorry, I can't figure this out. This is an inverse qubic force, not an inverse square force.

 

[dextercioby]

Yes, but the technique is the same.

Goldstein's "Classical Mechanics" derives the Rutherford cross section.

That's the book I'm using but it seems like I don't understand it.
