摘要: We report the first measurements of fine Ni particles from61Ni Mossbauer spectroscopy. The average hyperfine field 10 nm at 4.2K is measured to be 7.7(4) T, compared value for foil 7.5(3) T. Application an external 6 T causes a reduction splitting 1.5(6) consequence negative nuclei. These results are discussed in terms particle effects.
