    At small separations, the electron wavefunctions begin to overlap. Due to quantum mechanics (in particular, the Pauli exclusion principle), this requires a lot of energy, and leads to a repulsion. This is hard to evaluate in a general way, so approximations like the Lennard-Jones potential are used.
