State-specific dissociation dynamics for excited fragments of gaseous SiCl4 following Cl 2p and Si 2p core-level excitations were characterized by the dispersed UV/optical fluorescence spectroscopy. The core-to-Rydberg excitations at both Si 2p and Cl 2p edges lead to a noteworthy production of excited atomic fragments, neutral and ionic (Si-*,Si+*). In particular, the excited neutral atomic fragments Si-* are significantly reinforced. The core-to-valence excitation at the Si 2p edge generates an enhancement of excited molecular-ion SiCl4+. The experimental results provide deeper insight into the dissociation dynamics for excited neutral fragments of molecules via core-level excitation.
