Analysis of optical propagation in thick holographic gratings
(Springer-Verlag, 1975-05)
A method of analyzing optical propagation in thick holographic gratings by decomposition of the thick material into thin gratings is discussed. The method is readily applicable to study propagation in multiple gratings of ...
Decay angular distributions of p[pi]- states formed in diffraction dissociation of neutrons on carbon
(Elsevier, 1972-08-01)
We present decay angular distributions of the p[pi]- system formed from the interactions of 25-30 GeV/c neutrons on a carbon target. The data are studied as afunction of t', which allows a partial separation of coherent ...
Diffraction dissociation of neutrons in the reaction dp --> ppp[pi]- at 25 GeV/c
(Elsevier, 1974-09-18)
We observe the reaction dp --> pspec (p[pi]-)p in a bubble chamber exposure at 25 GeV/c incident deuteron momentum. The (p[pi]-) system with invariant mass below 2.0 GeV is interpreted as neutron diffraction dissociation. ...
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 ...
Absorption of He☒Ne Laser Radiation in an Exploded Lithium‐Wire Plasma
(The American Institute of Physics, 1970-03-15)
Calculations of the absorption coefficients for inverse bremsstrahlung in the field of ions and neutral atoms in ground and excited states and for photoionization are presented for the absorption of He☒Ne laser radiation ...
On the bare pomeron graph in two-dimensional QCD
(Elsevier, 1977-10-03)
We present a detailed study of the bare pomeron graph in two-dimensional QCD in the 1/Nc approximation. The absence of a new singularity unrelated to quark parameters is derived. The "cylinder" graph is shown to induce ...
Injection and mobility of potassium ions in liquid helium
(Elsevier, 1970-05-04)
Potassium ions from a hot tungsten wire are injected into He II; their mobility is found to be two to three percent lower than that of `normal' positive ions.
Intermolecular Vibrations in Liquid Secondary Chlorides
(The American Institute of Physics, 1970-04-15)
The 40Ar([tau], n)42Ca reaction
(Elsevier, 1974-05-13)
The results of an investigation of the 40Ar([tau], n)42Ca reaction at 18.65 MeV incident energy are reported. The weakness of the transition to the 1.84 MeV 0+ level is in disagreement with 4p-2h descriptions of this state.
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 ...
