Measurements of molecular hyperpolarizabilities for ethylene, butadiene, hexatriene, and benzene
(The American Institute of Physics, 1978-12-15)
Third‐order polarizabilities are measured in the gas phase using dc electric‐field induced optical second‐ harmonic generation and are found to be positive in each case.
Jet production by a gluon source in QCD
(Elsevier, 1978-12-25)
The properties of jets produced by a gluon source are examined in QCD. We give a simple derivation of the jet opening angle (up to an undetermined constant) using arguments of general applicability. At asymptotic energies, ...
12C(7Li, t)16O and stellar helium fusion
(Elsevier, 1978-07-31)
The reaction 12C(7Li, t)16O has been studied at E(7Li) = 34 MeV with the LASL tandem accelerator and QDDD magnetic spectrometer. Angular distributions to levels with Ex J[pi] = 1- levels, which are of great importance in ...
Appartus for high‐resolution surface tension measurement
(The American Institute of Physics, 1978-01)
We describe an apparatus for measuring surface tension of insulating liquids by capacitive sensing of capillary rise. Two guarded coaxial capacitors with different gap widths are connected to permit liquid to flow between ...
Radiation damage in polarized target materials
(Elsevier, 1978-01-15)
We examine some of the parameters which influence the decay of the polarization of polarized targets in an intense proton beam. We find that the usual characteristic flux for the polarization to drop to 1/e of its initial ...
Camel's back induced stabilization of electron-hole liquids : GaP
(Elsevier, 1978-09)
A camel's back-like nonparabolicity of the longitudinal electron mass enhances the density of states and strongly stabilized an electron-hole-liquid. In GaP therefore the EHL density is doubled to 8.6 x 1818cm-3 and the ...
Euclidean nonlinear classical field equations with unique vacuum
(Springer-Verlag, 1978-10)
We study the real, Euclidean, classical field equation 0$$]]> where φ: ℝ d →ℝ is suitably small at infinity. We study existence and regularity assuming that λ≧0, F ∈ C ∞ (ℝ), and aF ( a )≧0∀ a ∈∝. These hypotheses allow ...
On the utility of an in-core fast neutron generator
(Elsevier, 1978-11-01)
An examination of the flux magnitudes reported for a LiOD-D2O converter (thermal to 14 MeV neutrons) indicates that such a device offers little if any advantage over fission spectrum neutrons.
