Large increases in the photoionization threshold energies ofsmail V, N&, and Fe, clusters (~~3-25) mdueed by cbemisorption of H2 have been observed using photoionization time-of-flight mass spectrometry of a molecular beam. These shifis exhibit a definite dependence both on the number of atoms const

The resistivity of Fe has been found to increase more than that of Co and Ni when these metals are bombarded at -1150ยฐC by 12 Mev deuterons. The same effect was observed for Fe and Ni by neutron irradiation at room temperature. This result may be interpreted as indicating that Fe is affected to a gr
Polarization characteristics of Cr-or Ti-doped Raney nickel hydrogen electrodes have been measured as a function of the dopant content. When the doping condition is optimized, the limiting current density becomes approximately twice and the polarization resistance one-sixth of these respective value
