We have performed an angle-resolved photoemission spectroscopy study of BaCr2As2, which has the same crystal structure as BaFe2As2, a parent compound BaFe2As2 of Fe-based superconductors. We determine the Fermi surface of this material and its band dispersion down to 5 eV below the Fermi level. Very moderate band renormalization (1.35) is observed for only two bands. We attribute this small renormalization to enhanced direct exchange as compared to Fe in BaFe2As2, and to a larger contribution of the eg orbitals in the composition of the bands forming the Fermi surface.
