Homework Help: Ramsauer-Townsend equation. Joules or eV?

  1. Nov 21, 2012 #1
    1. The problem statement, all variables and given/known data

    There is a Ramsauer-Townsend equation in my notes for transmission.

    It's difficult to write out but looks somewhat like:

    T = {1 + {(sin k a)^2 / 4E/V0 (E/V0 - 1)}}

    Of course E and V0 should be in the same units.

    But should they both in Joules or eV?

    I would think Joules myself.

    Thank you!


    2. Relevant equations



    3. The attempt at a solution

    It doesn't matter once they both have the same units.

    E/V0 will work out the same as it is calculating a ratio.
