By representing f orbitals by cubic harmonics, overlap (or energy) integrals for f electrons have been calculated in terms of two-centre integrals. Results of s-f, p-f, d-f and f-f integrals are useful in making the tight-binding calculation as an interpolation method for substances with rare-earth or actinide elements.
