The optical reflectivity of SmB6, "golden'' SmS, and YbB12 has been measured between 1 meV and 12 eV at various temperatures down to 4.2 K. The results are analyzed with a Kramers–Kronig transformation. All three compounds reveal a hybridization gap of 4, 7, and 6 meV, respectively, with EF in the gap. The interband density of states could be estimated, and with simplifying assumptions it is 11 000 and 1200 states per Rydberg and cell for SmB6 and gold SmS, respectively, factors of 200 and 25 larger than the density of d states.
