An anisotropy (approx.170%) of the derivative of the upper critical field at T = T/sub c/ has been observed in the compound CeCu/sub 2/Si/sub 2/ during rotation of H in a plane near the basis plane. This anisotropy indicates that the superconducting gap may vanish along a line on the Fermi surface in this compound, in which a superconductivity arises in a heavy-fermion system at pressures p> or approx. =1 kbar. The anisotropy disappears at p>9 kbar.
