Potential Energy Curves and Generalized Oscillator Strength for Doubly Excited States of the Hydrogen Molecule

In this work we report calculations of potential energy curves in the 1.2a.u. ≤ R ≤ 100a.u. range at the Multireference Configuration Interaction (MRCI) level for doubly excited states of the H2 molecule. The molecular state which dissociates into two H(2s) atoms is clearly identified. The Generalized Oscillator Strength as a function of transferred momentum for three doubly excited states is also presented.
