    Structure and element-specific magnetic moments of epitaxial face-centered-cubic FexNi1−x alloy ultrathin films (1999)

    Notes: By core level x-ray photoelectron spectroscopy using an x-ray tube, ultrathin films of FexNi1−x alloys deposited epitaxially on a Cu(001) substrate have been investigated. Structural information is obtained by means of core level photoelectron diffraction. The angular dependent intensity scans reveal peaks corresponding to a face-centered-cubic lattice in the covered concentration range 0.08〈x〈0.9. Information on the local magnetic moments is obtained by observing the intensity asymmetry occurring when switching between directions of opposite magnetization (MLDAD). Both the Fe 2p3/2 and Ni 2p3/2 asymmetries show a maximum at about 50% Fe concentration. © 1999 American Institute of Physics.

    Radiochemical study of fast fission mechanism (1999)

    Notes: Abstract The reaction of238U with12C was studied radiochemically with the purpose of elucidating fast fission characteristics. Fast fission component was extracted in far-asymmetric mass region and interpreted as the mass diffusion following the Fokker-Planck equation. Anomalous charge dispersion widths in the corresponding mass region and a sudden increase of the whole mass distribution width at the critical energy were also observed to support the above interpretation. The reaction time of fast fission was determined to be 5·10−21 s from the width and position of the mass distribution.

    Fission fragment configurations at the scission point of233U,235U and239Pu(nth,f) (1999)

    Notes: Abstract In order to estimate the deformation rate of fission fragment at the scission point for thermal neutron-induced fission of233,235U and239Pu, double-velocity and double-energy measurements were carried out. As the result of the estimation of the deformation rate, two types of scission point configurations were found. One type is composed of deformed light and heavy fragments, and the other type is a combination of deformed light and spherical heavy fragments. Mass and total kinetic energy distributions were sorted in two distributions by means of the type of configuration.
