Epitaxial YBa[sub 2]Cu[sub 3]O[sub 7[minus][delta]] thin films (YBCO) and YBa[sub 2]Cu[sub 3]O[sub 7[minus][delta]]/PrBa[sub 2]Cu[sub 3]O[sub 7[minus][delta]] multilayers (Y/Pr) were irradiated with high-energy heavy ions (770) Mev [sup 108]Pb under various directions [phi] relative to the c-axis. The irradiation resulted in columnar defects tilted by [phi] from the c-axis. The angular dependence of their pinning activity was studied by measuring the anisotropy of the critical current density. The J[sub c](B, T, [theta]) behavior of the irradiated YBCO thin films showed an additional peak, which exceeds the intrinsic pinning peak, exactly at the irradiation direction. The Y/Pr multilayers, however, showed an isotropic J[sub c]-enhancement by a factor of 5, without any additional structure in the J[sub c](B, T, [theta]) curve. 14 refs., 2 figs.
