Rotational analysis of the red electronic emission system A3[Phi] --> X3[Delta] of diatomic niobium nitride (NbN)
(Elsevier, 1988-08)
The (0,0) band of the red emission system of the diatomic molecule niobium nitride (NbN) has been rotationally analyzed and found to arise from an A3[Phi]r-X3[Delta]r transition. Constants for the two states have been ...
Use of electron beam lithography to selectively decompose metalorganics into patterned thin‐film superconductors
(The American Institute of Physics, 1988-08-08)
Fine line superconductors, approximately 5 μm in width and 260 nm thick, were formed from Y‐Ba‐Cu on 〈100〉SrTiO3 by the combined methods of metalorganic deposition and selective area electron beam exposure. The lines were ...
Production cross section and electroweak asymmetry of D* and D mesons produced in e+e- annihilations at 29 GeV
(Elsevier, 1988-05-26)
The production of D* and D mesons has been studied in e+e- annihilations at [radical sign]s=29 GeV. The data, corresponding to an integrated luminosity of 300 pb-1, were obtained using the HRS detector at PEP. The cross ...
Measurement of 55Fe in reactor samples by an intrinsic Germanium detector
(Elsevier, 1988)
Determination of 55Fe in reactor samples requires some care because of the low-energy x-rays emitted following decay by electron capture and the presence of 59Fe and other possible [gamma]-ray emitting contaminants in ...
Toxicity from treatment of neuroblastoma with 131 I-meta-iodobenzylguanidine
(Springer-Verlag, 1988-09)
Toxic effects from 131 I-meta-iodobenzylguanidine ( 131 I-MIBG) treatments of neuroblastoma in six patients were recorded. The toxicity was largely confined to the hematologic system where circulating leukocytes and platelets ...
Enhanced and quenched Raman scattering by interface phonons in semiconductor superlattices: What are the defects?
(Elsevier, 1988)
We report on the magnetic field and power density dependences of resonant Raman scattering by interface phonons in GaAs---AlxGa1-xAs superlattices. Strong photoexcitation leads to quenching of the nominally forbidden (and ...
Exciton reactions in ultrathin molecular wires, filaments and pores: A case study of kinetics and self-ordering in low dimensions
(Elsevier, 1988-12-01)
When are molecular wires thin enough to show one-dimensional exciton kinetics? Cylindrical naphthalene wires ( 5-5000 nm radius) show a definite one- to three-dimensional transition (about 25 nm for triplet excitons at 4 ...
Dissipative quantum tunneling: quantum Langevin equation approach
(Elsevier, 1988-03-21)
The quantum Langevin equation is used as the basis for a discussion of dissipative quantum tunneling. A general analysis, including strong coupling and non-markovian (memory) effects, is given for the case of tunneling ...
Large intermediate-depth earthquakes and the subduction process
(Elsevier, 1988-12)
This study provides an overview of intermediate-depth earthquake phenomena, placing emphasis on the larger, tectonically significant events, and exploring the relation of intermediate-depth earthquakes to shallower seismicity. ...
One-dimensional luminescence kinetics; a submicron probe
(Elsevier, 1988-02)
Cylindrical naphthalene wires (10-1200 nanometer diameter) exhibit one-dimensional exciton annihilation kinetics for 10-30 nm wires, three-dimensional behavior for 100-1200 nm wires and a crossover diameter increasing from ...
