# The momentum wave function for the hydrogen atom

The hydrogen atom ground state may be described by the spatial wave function as:

phi(r)= [(1/(Pi*(a_0^(3)))^(1/2)]*e^(-r/a0)

This is where a_0 is the Bohr radius. Using the following equation, please calculate the momentum wave function.

integral[(e^(-a*r + i*b*r))*(d^(3))*(r) = 8*Pi*a/((a^(2) + b^(2))^(2))

See the attached file for the breakdown of this solution with adequate symbols and notation.
