- Vibrationally resolved N-2(+) (B-X) (1-2) and (0-1) emission bands were recorded after photoexcitation of N-2 in the 20-46 eV energy range. The branching ratio between these transitions reveals strong non-Franck-Condon effects. Ab initio calculations using a configuration interaction method based on Kohn-Sham orbitals indicate that the autoionisation of certain superexcited states is responsible for some structures present in the branching ratio curve.

- The mass spectra from the SF6 molecule acquired by energy-resolved electron ion coincidence (EREICO) technique using (1t(1g) + [5t(1u),1t(2u)]), (3e(g) + 1t(2g)), 4t(1u), and 5a(1g) electrons after both valence and S 2p(-1) 6a(1g) core excitation reveal a strong selectivity in the dissociation from these states. From the comparison of the obtained spectra, the influence of the core-excited state in the relaxation pathway of the molecule is studied. The S 2p --> 6a(1g) core excitation does not affect the relaxation dynamics after participator Auger decay to the (1t(1g) + [5t(1u),1t(2u)])(-1) and (4t(1u))(-l) states, but it alters the relaxation dynamics after participator Auger decay to the (3e(g) + 1t(2g))(-1) and (5a(1g))(-1) states with respect to the decay processes after direct excitation of the same orbitals. These observations point to core excitation induced dissociation in the SF6 molecule.
