Homework Statement
This problem is in Schaum's outline of quantum physics. We need to evaluate [tex]|\psi(x)|^2[/tex] for the wave function [tex]\psi(x)=\int_{-\infty}^{\infty}e^{-|k|/k_0}e^{ikx} dk[/tex]
Homework Equations
[tex]|\psi(x)|^2=\psi(x)\psi(x)^*[/tex]
The Attempt at a Solution
I tried to evaluate the integral [tex]\int_{-\infty}^{\infty}dk\int_{-\infty}^{\infty}dk'e^{-(|k|+|k'|)/k_0}e^{i(k-k')x}[/tex]
