Homework Help: Nuclear Physics Problem

  1. Jan 4, 2008 #1
    1. The problem statement, all variables and given/known data

    A nucleus[atomic no Z, mass no. A] splits into two fragments(z1,A1) and (Z2,A2).Find the separation between them at the time of splitting.

    2. Relevant equations
    3. The attempt at a solution

    I am giving the way I would approach.Please check and confirm:

    rest energy of (Z,A)=rest energy of (Z1,A1)+rest energy of (Z2,A2)+Coulomb repulsion term

    The Coulomb repulsion term includes the required separation.

    Please check if I am correct.

    But you need to know the separation to find the Coulomb repulsion.
    Use the formula for R=1.2A^(1/3) to find each radius.

    is that really necessary?we are interested about the central distance...
