Times Cited Count:2 Percentile:62.57Fe48-at.% Al alloy were implanted with 50 keV H ions to the fluence of 310 and 110 /cm at room temperature. Positron annihilation Doppler broadening and lifetime measurements for these alloys have been carried out using slow positron beam apparatus with an energy range of 0.2 to 30.2 keV. The positron annihilation S-parameter decreased by H ion irradiation. Also the positron lifetimes for hydrogen deposited region in the alloy decreased by the irradiation. These results show that implanted H atoms were trapped by vacancy type defects.

Times Cited Count:20 Percentile:77.91(Chemistry, Inorganic & Nuclear)Anion-exchange chromatography of element 105, dubnium (Db), produced in the Cm(F, 5n)Db reaction is investigated together with the homologues Nb and Ta, and the pseudo-homologue Pa in 13.9 M hydrofluoric acid (HF) solution. The distribution coefficient (K) of Db on an anion-exchange resin is successfully determined by running cycles of the 1702 chromatographic column separations. The result clearly indicates that the adsorption of Db on the resin is significantly different from that of the homologues and that the adsorption of anionic fluoro complexes of these elements decreases in the sequence of Ta Nb Db Pa.

GC/MS (Gas Chromatography/Mass Spectrometer) with the help of Chemical treatments has been applied to measure amount of helium (He) atoms in metals. Metal samples of cupper (Cu) contained He atoms were prepared using a 200kV ion implantation machine. The samples were solved in 0.5cc volume of 20% nitric acid in a H type reaction tube filled with nitrogen gases at 1 atmospheric pressure and He atoms in Cu metal were exhausted completely into the nitrogen gases. He analysis using GC/MS reveals that the metals contained 10 to 10 atoms of He. The He signal intensity and He ions implanted to the metals revealed good proportional relation.

Times Cited Count:43 Percentile:72.54(Chemistry, Multidisciplinary)Fluoride complexation of element 104, rutherfordium (Rf), produced in the Cm(O,5n)Rf reaction has been studied by anion-exchange chromatography on an atom-at-a-time scale. The anion-exchangechromatographic behavior of Rf was investigated in 1.9-13.9 M hydrofluoric acid together with those of the group-4 elements Zr and Hf produced in the O-induced reactions on Ge and Gd targets, respectively. It was found that the adsorption behavior of Rf on anion-exchange resin is quite different from those of Zr and Hf, suggesting the influence of relativistic effect on the fluoride complexation of Rf.
