Abstract
Formation and decay of molecular doubly excited resonances is a challenging subject in molecular physics since the Born-Oppenheimer approximation and mean field approximation are not valid. We succeeded in observing the doubly excited resonances in electron-H_2 collisions by means of coincident electronenergy-loss spectroscopy. A newly found doubly excited state 'F' was proposed to substantiate a peak around 26eV. However such state has not yet been obtained theoretically. In order to understand the dynamics of the doubly excited H_2 in more detail we have recently carried out the (γ, 2γ) coincidence experiment on H_2. It has been found that a semiclassical approximation describes well the dynamics of the Q_2^1П_u(1) state of H_2. The origin of the 26eV peak, however, remains an open and tough question.
