Abstract
The doubly excited states of molecular hydrogen have been studied by m eans of electron-energy-loss spectroscopy in coincidence with the dete ction of H(2p) formation at 80 eV incident energy and 3 degrees scatte ring angle. This is the first observation of doubly excited states of H-2 in electron energy-loss spectra. It is shown that a forbidden doub ly excited state makes a large contribution as well as allowed states. The measured spectrum has been analysed by theoretical fits based on the reflection approximation.
