Optical effect of the contamination of infrared windows by the outgassing of materials in outer space
The products and kinetics of outgassing from S13G paint were studied by using infrared absorption measurements of the material outgassed (using an evaporation cell and vacuum chamber). Two separate long-term experimental depositions from heated samples of the S13G paint were made. Before each experiment, the vacuum chamber and sample holder were carefully cleaned and outgassed to ensure that subsequent deposits on the colled-window were due only to the products evaporated from the sample. Results of experiments are listed and discussed
Scarring of quasimodes on hyperbolic manifolds
Let be a compact hyperbolic manifold, an embedded totally
geodesic submanifold, and let be the semiclassical
Laplace--Beltrami operator.
For any , we explicitly construct families of
\emph{quasimodes} of spectral width at most
which exhibit a "strong scar" on in
that their microlocal lifts converge weakly to a probability measure which
places positive weight on (). An immediate
corollary is that \emph{any} invariant measure on occurs in the ergodic
decomposition of the semiclassical limit of certain quasimodes of width
