Link between momentum transfer and distance

  1. Feb 8, 2010 #1
    hi folks,

    readingthis post:

    I was wondering why this distance of interaction is smaller at higher momentum transfers.

    Could anyone explaine the link between momentum transfer and distance?

    Best,
    derivator

    Basically from the uncertainty principle:

    [tex] \Delta x \approx \hbar/q [/tex]

    where q is the momentum transfer - there may be a factor of 2 missing- that is why I put approx. This should give some measure of the average distance of interaction.
