The accessibility of the two-photon spectroscopy to the forbidden states of the one-photon transition makes ita powerful tool. The two-photon excited core excitons were chosen as an example of a combinational use oflaser light and synchrotron radiation. The experiments were performed at Beamline 1B of UVSOR, Institutefor Molecular Science. The two light sources were synchronized at a repetition rate of 90 MHz. The singlephotoncounting method was used for detecting luminescence as the signal of two-photon absorption by thesample. The two-photon excitation spectrum of Auger-free luminescence from the BaF<SUB>2</SUB> crystal exhibits severalpeaks due to core excitons. The analysis of the spectrum reveals the spin-orbit splitting and dispersion ofthe 4<I>f</I> and 6<I>p</I> states of the Ba ion in BaF<SUB>2</SUB>. The lifetime of the core exciton is obtained from the time-resolvedmeasurements.
