Homework Help: Equivalence of Born and eikonal identities

  1. Mar 29, 2012 #1
    I am required to show that
    (i)in the upper limit of very high energies, the Born and eikonal identities are identical.
    (ii)that the eikonal amplitude satisfies the optical theorem.

    Regarding (i) I think it will involve changing from an exponential to a trig(Euler's theorem) but I could be wrong. The textbook says that sinχ=χ (I think that χ is the profile function).

    Regarding (ii) I am clueless. I am trying to do postgrad physics after a period of 6 years since undergrad!!
    Please help!

    Ok I have just tried what I thought would be right and failed. Can anyone reference me to a text on this stuff that is understandable?
