• The rare-earth N_<4,5> emission spectra of PrB_6 and NdB_6 were measured to investigate the 4f states. These spectra show some emission peaks above and below the one-electron 4d threshold. The emission spectra are compared with existing results of absorption and resonant photoemission. Comparison shows that the emission spectra are composed of two types of 4f→4d emission processes, 4d^94f^n→4d^<10>4f^<n-1>+hv and 4d^94f^<n+1>→4d^<10>4f^n+hv', where n is the number of 4f electrons in the ground state. The intensity of the 4f→4d emission is estimated for light rare-earth hexaborides. This result suggests that the intensity of the 4f→4d emission is weaker than the 5p→4d emission.
