Abstract—We report the first observation of the polarization dependence of the d.c. photocurrent induced by
illumination in Cu. The dependence of a d.c. photocurrent on the direction of the plane of light polarization is
measured. In agreement with the theoretical considerations, the current parallel to the plane of light incidence
is a symmetric function of the angle between this plane and the plane of light polarization. The angular-depen-
dent part of the current perpendicular to the plane of light incidence is an antisymmetric function of the angle.
