Abstract：
The surface energy coefficient of nuclear matter σ(T,δ) as a function of temperature T and nuclear asymmetry δ is calculated for the semi-infinite model of nuclear matter, using the temperature-dependent Thomas-Fermi statistical model theory with the Seyler-Blanchard momentum-dependent nonlocal interaction. It was found that the surface energy coefficient can be written approximately as σ(T,δ)=σ₀(T)[1+K(T)δ²], where the σ₀(T) and K(T) can be fitted as quadratic functions of the temperature T.
