Laser‐driven hydrodynamic perturbation in an overdense Z‐pinch plasma
(The American Institute of Physics, 1979-04)
Holographic interferometry of the interaction of a radially incident intense CO2 laser beam (1011 W/cm2, 38‐nsec FWHM pulse) with an overdense helium Z‐pinch plasma (ne≳1019 e/cm3, Te∼20 eV, L=100 μm) has indicated the ...
Spin measurements in hadronic high momentum transfer scattering
(The American Institute of Physics, 1979-05-01)
The results of recent experiments investigating spin effects in hadronic high momentum transfer scattering are reviewed. There is evidence for very large spin dependences at high momentum transfer in measurements involving ...
Molecular structures of gas‐phase polyatomic molecules determined by spectroscopic methods
(The American Institute of Physics, 1979-07)
Spectroscopic data related to the structures of polyatomic molecules in the gas phase have been reviewed, critically evaluated, and compiled. All reported bond distances and angles have been classified as equilibrium (re), ...
Percolation and cluster distribution. III. Algorithms for the site-bond problem
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1979-11)
Algorithms for estimating the percolation probabilities and cluster size distribution are given in the framework of a Monte Carlo simulation for disordered lattices for the generalized site-bond problem. The site-bond ...
Singular f-sum rule for superfluid 4He
(Elsevier, 1979-10-15)
The validity and applicability to inelastic neutron scattering of a singular f-sum rule for superfluid helium, proposed by Griffin to explain the [varrho]s dependence in S(k, [omega]) as observed by Woods and Svensson, are ...
Chemistry of the thermosphere and ionosphere
(Elsevier, 1979)
The ionosphere offers an excellent laboratory for the study of atomic and molecular processes. Densities are low, permitting highly reactive species to accumulate in measurable quantities. Temporal and spatial scales are ...
Interferometric characterization of density dynamics of an ultradense Z‐pinch plasma
(The American Institute of Physics, 1979-04)
We have measured the spatially and temporally resolved density in a Z‐pinch plasma by holographic interferometry. The high electron density (4×1019 e/cm3), short density scale length (100 μm), and low temperature (about ...
Absorbed dose rate produced by natural uranium as a function of depth in tissue
(Elsevier, 1979-02)
Slabs of natural and depleted uranium are used routinely to calibrate personal dosimeters and radiation survey instruments for beta radiation. However, little information is available on the absorbed dose rate produced by ...
Monte Carlo experiments on cluster size distribution in percolation
(IOP Publishing Ltd, 1979-08-01)
Cluster statistics in two- and three-dimensional site percolation problems are derived here by Monte Carlo methods. The average number ns of percolation clusters with s occupied sites each is calculated by up to 19 runs ...
Variable range cluster model of exciton migration: Dimensionality and critical exponents for naphthalene
(Elsevier, 1979-01)
Relative luminescence intensities for randomly substituted ternary systems with two major components and a minor one (sensor), for four triplet and one singlet exciton systems, identify the maximal effective exciton ...
