Abstract
The fragmentation of the CD4 molecule after selective ionization of the 1t2 and 2a1 electrons with photons from 70 to 290 eV has been studied with the energy-resolved electron-ion coincidence technique. The mass spectra acquired in coincidence with 1t2 electrons reveal CD4+, CD3+, and CD2+ fragments, depending on the excitation energy used. The production of CD3+ is strongly enhanced after C 1s excitation to different core excited states, with respect to the production observed after direct ionization of the 1t2 orbital. This enhancement is correlated with the changes of the molecular geometry when it relaxes from the core-excited state.
