Link between momentum transfer and distance

[Derivator]

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?

Basically from the uncertainty principle:

$$\Delta x \approx \hbar/q$$

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.
