N2 - Measurements of the temperature dependence of the optical absorption edge, Eg(T), in EuO, at the close vicinity of its critical temperature, Tc, are reported. In agreement with theoretical expectations the analysis of the results, with the constraints of continuous Eg and dEg/dT, yielded the same critical exponents (α = α' ≈ -0.044) and amplitude ratio (|A/Á| ≈ 1.22) as the specific heat data analysis.
