Reflection–absorption spectroscopy in the ultraviolet (UV) of C6H6 molecules physisorbed on a gold surface has been observed in a single-pass experiment for the electronic transition 1 A 1g → 1 B 2u near 250 nm. The linewidths of transitions in t

We report the absolute column densities of gas phase C6H6 and upper limits on absolute C4H2 and C2H3 concentrations in a hot filament diamond chemical vapor deposition (CVD) reactor. The steady state density of C6H6 is monitored as a function of C2H2

We report an experimental comparison of the rotational temperature and the gas kinetic temperature of and in a positive column discharge. The discharge is operated in an oven. The oven temperature, determined with a thermocouple, provides a lower bou

We have carried out extensive investigations of the gas phase composition during diamond CVD in a conventional hydrogen rich environment. Absolute densities of CH/sub 3/, CH, and the hydrogen dissociation ratio have been measured in hydrocarbon-based

A mathematical model is presented in which a single mutation can affect multiple phenotypic characters, each of which is subject to stabilizing selection. A wide range of mutations is allowed, including ones that produce extremely small phenotypic ch

Cognitive models of depression have been invoked to explain the development of depressive symptoms and disorders in patients with chronic pain. However, few long-term, prospective studies have examined A. T. Beck's (1967, 1987) model in this context.

Depression is common in rheumatoid arthritis (RA) populations and has been hypothesized to result from patients' belief that they cannot control their disease or its impact. In a sample of 106 patients with RA, we found that scores on a measure of he

This article reports on ultraviolet reflection–absorption spectroscopy of C6H6 molecules physisorbed on Ag, Cu, and Au surfaces. The electronic 1A1g→1B2u transition of C6H6 at wavelengths near 250 nm is observed. We model the system and obtain ce
