Outline of Final Research Achievements

Nuclear transformation of nickel to copper et al. has been reported owing to combination of nickel powder and hydrogen. The nuclear transformation was verified when hydrogen ions irradiate to mesoporous nickel. Hydrogen ions with 300 eV were irradiated to a Ni porous plate attached Ni powder (< 50 nm) kept at 600 deg C for 6-42 hours. In the result of the surface elemental analysis by SEM/EDX, C and Fe were contained relatively abundant. Meanwhile, in the internal metal, Fe and Co were abundantly detected, but Cu was not detected by ICP atomic emission spectrometry. It was considered possible that Fe was supplied from stainless steel by sputtering, we could not obtain the clear evidence of the nuclear transformation.
