Homework Help: Proton Charge Distribution and Form Factor Problem

  1. Oct 6, 2014 #1
    1. The problem statement, all variables and given/known data

    Hi all - I have been trying to evaluate part II of this problem for a long time now...

    For a simplified model of a proton's charge distribution, hw1eqn2.gif

    1. Find the constant of proportionality required to normalise ρ correctly.
    2. Show that hw1eqn3.gif

    2. Relevant equations

    3. The attempt at a solution
    I have done part I by method of integrating rho(r)dV between 0 and infinity and setting it equal to 1. dV in this case would just be 4*pi*r^2*dr with no angular dependence.
    I have got the constant of proportionality as 1/4*pi*R^2

    When I attempt to do part II all I get to is a horrible integral with an exponential and a sin function in... Am I going about this correctly, should i follow through with the cyclic integral?
