The electron affinities of SrSe, SrTe, CaSe, and CaTe have been determined using measurements of the temperature dependences of the electrical conductivity and the thermionic emission. The values obtained were 1.77, 2.40, 2.32, and 3.53 eV, respectively. Using these values together with previously obtained values for BaO, BaS, BaSe, BaTe, and CaO and a correlation with the lattice spacings, estimates of the electron affinities of SrO, SrS, CaS, MgO, MgS, and MgSe were obtained by extrapolation.
