    Magnetic characteristics of ultrafine Fe particles reduced from uniform iron oxide particles (1987)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 61 (1987), S. 3323-3325

    Notes: Uniform, cubic 0.05-μm iron oxide particles were formed by forced hydrolysis of ferric perchlorate. These particles were reduced to α-Fe by heating in hydrogen at temperatures between 300 and 500 °C. The effect of reduction temperature and various prereduction treatments on the microstructure of the iron particles will be discussed. Complete reduction to α-Fe was established by 57Fe Mössbauer spectroscopy and x-ray diffraction. Magnetic measurements on epoxy and polyurethane films containing these particles with various mass fractions gave coercivities as high as 1000 Oe. The relationship between the magnetic measurements and the microstructure will be discussed. Na2SiO3 is found to be the best coating material for the process of reducing iron oxide particles to iron.

    Inert gas excimer radiation from a free jet expansion (1987)
    [S.l.] : American Institute of Physics (AIP)
    Review of Scientific Instruments 58 (1987), S. 812-816 
    Details
    ISSN: 1089-7623

    Topics: Physics , Electrical Engineering, Measurement and Control Technology
    Notes: A molecular beam source incorporating a dc discharge is used to study the emission spectrum of helium excimers near 600 A(ring) and of argon excimers near 1070 A(ring). It is shown that under certain conditions the strength of the excimer radiation approaches that due to the helium resonance lines. The new source is expected to be useful for studying other excimers in the vacuum ultraviolet region of the spectrum.

    High resolution infrared spectra of ethylene clusters (1987)
    College Park, Md. : American Institute of Physics (AIP)
    The Journal of Chemical Physics 87 (1987), S. 873-879 
    Details

    Topics: Physics , Chemistry and Pharmacology
    Notes: Infrared predissociation spectra have been measured for ethylene clusters near the ν7 (950 cm−1) monomer band using CO2 lasers. One of the CO2 lasers was piezoelectrically scanned over a 240 MHz range around each rotational lasing transition, to obtain high resolution spectra of the ν7 band. The resulting spectra showed fine structure with widths of the order of 20 MHz, representing a lower limit on the predissociation lifetime of around 10 ns. The fine structure is shown to be due to ethylene dimers, and the broad background is attributed to a superposition of inhomogeneous contributions from larger clusters.

    Diffusion Monte Carlo simulation of condensed systems (1987)
    College Park, Md. : American Institute of Physics (AIP)
    The Journal of Chemical Physics 86 (1987), S. 5703-5707

    Notes: Diffusion Monte Carlo calculations are reported for liquid 4He using a Lennard-Jones potential and for solid molecular hydrogen using a reliable spherical pair potential and Axilrod–Teller three body interactions. Calculated thermodynamic and structural properties are in good agreement with experiment over a range of densities. Discrepancies between calculated and experimental values for hydrogen at the highest densities are attributed to the neglect of anisotropy in the calculations.
