The orientational dependence of the yield of Rutherford backscattering of He ions from single crystals of PrBa2Cu307.._ δ in the tetragonal phase has been studied. The half-widths of the angular dependences of the Rutherford backscattering yield and the minimum relative yield of the Pr + Ba and Cu sublattices were found to diifer markedly during the channeling.
