Growth of high purity single crystals of arsenic
(Elsevier, 1983-06)
Large, high quality, single crystals of arsenic have been grown from the melt in a high pressure bomb made from synthetic quartz. The crystals have residual resistance ratios (RRR) of up to 5500, the largest reported to date.
Analytical approaches for the electronic structure of C60
(Elsevier, 1993-12-06)
We use the recursion and path-integral methods to analytically study the electronic properties of a neutral C60 molecule. We obtain closed-form analytic expressions of the eigenvalues and eigenfunctions for both [pi] and ...
Neutron diffraction dissociation and Coulomb dissociation from nuclei
(Elsevier, 1971-10-18)
Preliminary results of a spark-chamber experiment are presented on the reaction n+A --> (p + [pi]-) + A where the (p[pi]-) pair is produced coherently off the nucleus A. A 0[deg] neutron beam derived from a beryllium ...
Minimal coupling of electromagnetic field in Riemann-Cartan spacetime for perfect fluids
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1992-07)
We minimally couple the electromagnetic field to gravity in Riemann-Cartan spacetime in the self-consistent formalism for perfect fluids by treating the internal energy of matter as a function of the electromagnetic field. ...
Anomalous radiative Z0 decay
(Elsevier, 1984-05-24)
We examine some possible mechanisms which can explain the anomalous radiative Z0 decays that were observed recently. They are (I) an anomalous Z0[gamma][gamma] interaction, and (II) the virtual effect of monopole-fermion ...
Radiative corrections to parapositronium decay
(Elsevier, 1980-09)
Radiative corrections to the two-gamma decay of parapositronium are examined. Special care is taken in the handling of the so-called binding diagram; in particular, the limiting procedure related to the infrared divergence ...
Comparison of light quark and charm quark fragmentation
(Elsevier, 1985-10-31)
Separate samples of charm quark and light quark (u, d, s) jets have been isolated in an experiment studying e+e- annihilations at . The results come from data corresponding to an integrated luminosity of 111 pb-1 collected ...
Soft breaking of two-loop finite N = 1 supersymmetric gauge theories
(Elsevier, 1984-11-29)
The effect of soft supersymmetry-breaking terms on one-loop finite N = 1 supersymmetric gauge theories is investigated, and the general conditions that finiteness be preserved given. Particular attention is paid to the ...
Experimental limits on monojet production in e+e- annihilation at 29 GeV
(Elsevier, 1985-06-20)
A search was made for e+e--->X1X2 where X1 consists of one or more light unobservable particles and X2 decays promptly to a visible jet of particles. One event was found for an integrated luminosity of 176 pb-1, a rate ...
A spin polarized disc
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1995-03)
We present a solution to the gravitational field equations in a Riemann-Cartan spacetime. The solution describes a disc of infinite radius and finite thickness. The solution has three forms which depend on the size of the ...
