We present preliminary results for thin films grown with a recently commissioned ion beam codeposition system designed for in situ growth and etching of YBCO films. The apparatus consists of a high-vacuum chamber (10-7 Torr) equipped with four Kaufmann ion ...
The shifts from gas-phase values of the vibrational and rotational states of H2 impurities substitutionally trapped in solid Ar are calcd. at zero temp. and at pressures 0 < P ? 438 kbar, using the recently developed H2-Ar potential of R. LeRoy and J. Carl ...
Charge-exchange collisions and radio frequency (RF) excitation combine to give peaks in the ion energy distribution measured at the ground electrode of an argon plasma in a capacitive reactor. These peaks are used as a diagnostic to reconstruct the profile ...
The evolution of the argon metastable states density has been studied by absorption spectroscopy in power-modulated plasmas of argon and a mixture of 4% silane in argon. A small concentration of silane suppresses the argon metastable states density by mole ...
The resonance Raman overtone progressions of I2 in liq. Xe following excitation of the B state are discussed, and compared with similar data in solid Ar. It is shown that the Raman contribution from the B state is damped by predissocn. within one recurrenc ...
A CO2 laser-heated diamond anvil cell was used for performing argon solubility experiments in silicate melts. This technique allowed solubility experiments to be carried out at much higher pressures than in a piston-cylinder-type apparatus. When the beam o ...
Understanding particle dynamics requires comparison of spatially resolved measurements with two-dimensional (2-D) simulations, In this work, a cross section of a capacitive discharge is illuminated with an expanded laser beam, and global scattered light is ...
An argon laser is used to induce Laser Chem. Vapor Deposition (LCVD) of platinum using platinum bihexafluoroacetylacetonate as precursor. The process can be photolytic or pyrolytic depending on the laser power used. These processes are studied by recording ...
A structural analysis of the Ru—RuOx/TiO2 catalyst has been carried out. This catalyst is active for CO2 methanation at low temperatures. The preparation conditions are critical in generating the selective dispersion of the metallic particles on rutile cry ...
Three new progressions consisting of broad bands were obsd. in the absorption spectrum of NO in solid Ar. They are identified as the mol. Rydberg A 2.sum.+,C 2P and D 2.sum.+-X 2P (v', 0) transitions, blue shifted with respect to the gas phase by .apprx.0. ...
