Electronic structure around the Fermi energy of noncentrosymmetric superconductor CePt3Si in the normal state in the vicinity of the magnetic phase transition was investigated using low temperature electron tunneling spectroscopy. A pronounced E1/2 anomaly observed in the density of states at the Fermi level indicates an interplay of correlation and localization. A dip in the low bias voltage region resembling a narrow correlation pseudogap of the width approx2 meV is believed not to originate from magnetic interactions. The results are consistent with the assumption that two sets of electrons are present in CePt3Si.
