Homework Help: Energy required by an electron

  1. Sep 4, 2006 #1
    I am quite clueless over this. :frown:

    Calculate what energy needs to be given to electrons so that they are able to probe the nuclear size.

    Is the radius of the nucleus (~1Fermi) relevant in this problem? Help needed..

    Your guess is right. For example x-rays can be used to probe the structure of solids because their wavelengthsm are of the same order of magnitude than atomic spacings in solids.

    Thanks again for replying!
    So, I have to take the de Broglie wavelength as 10-15m and substitute in [itex]\lambda = \frac{h}{\sqrt{2mE}}[/itex] and obtain the KE, right?

    You should check wether relativistic corrections are neccessary or not.
