Query: Understanding correlation between two bound state electrons using a
  simple model   Understanding electron correlation requires solving inseparable Schrodinger
equation. In general, inseparable Schr\"odinger equations cannot be solved
analytically. So their solutions are obtained numerically. In this paper we
investigate electron correlation problem using the Dirac delta function
repulsion between two electrons, where each electron is bound in their
respective Dirac delta potential well.
