1. The problem statement, all variables and given/known data The charge distribution of an atomic nucleus is modelled by the Gaussian distribution: p(r) = A exp(-r2/a2) Obtain the Fourier transform of p(r), and use the result to obtin an expression for the potential as a Fourier integral. 2. Relevant equations Fourier transform and electrostatics 3. The attempt at a solution I found the fourier transform to be A*pi3/2*a3 exp(-1/4*a2k2) How would you obtain the electrostatic potential (I suppose V) as a Fourier integral?
