    Notes: The high-temperature heat contents of n-type SiGe(GaP), p-type SiGe(GaP), and p-type SiGe alloys were measured from 400 to 1400 K by using a copper block drop calorimeter. The heat capacity and related thermodynamic functions were calculated. Smoothed values of H0T−H0298.15, Cp, S0T−S0298.15, and −(F0T−H0298.15)T−1 were tabulated at 100-K intervals. Thermal diffusivities were measured by using a laser technique. Thermal conductivities were calculated from the heat capacity, thermal diffusivity, and density.

    Notes: The high-temperature heat contents of La2S3(α), La2S3(γ), La3S4, and La2.65Eu0.35S4 were measured from 400 to 1800 K by using a copper block drop calorimeter. The heat and entropy of transition of the α-to-γ transformation of La2S3 was determined. Equations for the thermodynamic functions H0T−H0298.15, Cp, S0T−S0298.15 and −(F0T−H0298.15)/T were derived in terms of the least-squares fit parameters of the heat content data.

    Difference frequency laser spectroscopy of the ν1 fundamental band of HOCO+ (1985)
    College Park, Md. : American Institute of Physics (AIP)

    Notes: The ν1 fundamental band of HOCO+ has been observed with a hollow-cathode discharge in a fast flowing gas mixture of H2(∼250 mTorr) and CO2(∼20 mTorr). A least squares fit of more than 500 lines including the three astrophysical millimeter-wave lines and six laboratory submillimeter-wave lines to an effective vibration-rotation Hamiltonian has yielded a set of precise spectroscopic parameters. The agreements between the present experimental rotational constants and those calculated by ab initio methods are remarkable. The band origin has been found to be 3375.374 13(8) cm−1, which is about 27 cm−1 higher than the recent ab initio value. A perturbation found in the J′2,J′−2 levels in the excited state is discussed in some detail. The rotational transition frequencies in the ground state have been given for further astrophysical and laboratory searches.

    Notes: The observation and analysis of 187 lines in the 2–0 band of the A 2Πi ← X 2Σ+ system of the SiN radical are described. The 2–0 band, which lies near 3.3 μm, has been recorded with a tunable difference frequency system and discharge amplitude modulation. The analysis gives improved molecular constants for the ground and first excited states, including the first lambda doubling parameters for the A 2Π state.

    Difference-frequency laser spectroscopy of the 3ν2+ν3 band of C2H (1993)
    College Park, Md. : American Institute of Physics (AIP)
    The Journal of Chemical Physics 99 (1993), S. 4312-4317

    Notes: A spectrum of C2H 2Π–2Σ+ transition centered at 2928 cm−1 has been measured in the gas phase using a high resolution difference-frequency infrared laser spectrometer. The C2H molecules are produced in a hollow cathode discharge through a mixture of C2H2 (∼20 mTorr) and H2 (∼500 mTorr). The discharge amplitude modulation technique is used to enhance sensitivity and selectivity. About 125 lines are rotationally analyzed and accurate molecular constants are determined through a least-squares fit. The band is assigned to the 3ν2+ν3 combination band. The assignment is consistent with the observed 2Π–2Σ+ symmetry and is in good agreement with the recent theoretical calculation of the vibrational frequency and the spin–orbit coupling constant. The relatively large spin–orbit coupling constant of the (0 3 1) state is indicative of strong vibronic interaction between the A˜ and X˜ states. A small perturbation appears near the end of observed Q-branch series, which is probably caused by a Σ vibronic state. New assignments of the progressions (0 v2 0) and (0 v2 1) toward higher v2 are proposed based on the existing gas phase and rare gas matrix data with the help of recent ab initio theoretical predictions.

    A global dynamo in a reversed-field pinch plasma (1994)
    [S.l.] : American Institute of Physics (AIP)
    Physics of Plasmas 1 (1994), S. 2876-2881

    Notes: It is found that a reversed-field pinch (RFP) dynamo uniformly generates most of the toroidal flux in a RFP plasma with a high magnetic Reynolds (S) number. Hereafter, this is referred to as the global dynamo. The toroidal flux generated by the global dynamo is proportional to the plasma current. The effective inductance in a RFP plasma increases with S number and remains constant against the changing plasma current. This means that the pinch parameter aitch-theta is held constant, that is, the global dynamo has a self-organizing effect sustaining a particular RFP configuration. By comparing simulation results and analysis of magnetic fluctuations, it is confirmed that a global dynamo is generated by the nonlinear evolution of the single-helicity of the m=1 mode alone.

    A field-reversal mechanism in a reversed-field pinch (1995)
    [S.l.] : American Institute of Physics (AIP)
    Physics of Plasmas 2 (1995), S. 1182-1191

    ISSN: 1089-7674

    Topics: Physics
    Notes: A field-reversal mechanism in a reversed-field pinch (RFP) is studied through a three-dimensional resistive compressible magnetohydrodynamic (MHD) simulation of the single- and multiple-helicity modes. As the magnetic Reynolds number increases, the m=1 fluctuating magnetic field grows exponentially and extends radially, and then the flow begins to form the vortex structure around the core of the plasma. This radial flow acts such as to push out the toroidal magnetic field. As the dynamo electric field induced by this interaction increases near the core of the plasma, the toroidal magnetic field at the wall decreases toward the negative value and the toroidal magnetic field reverses. As a result, it is found that the field reversal is achieved by the single-helicity evolution of the m=1 mode alone, without the (m=0; n≠0) modes, and the interaction of the radial flow and the toroidal magnetic field is the most dominant source for the dynamo action on the field-reversal process. © 1995 American Institute of Physics.
