Interpreting Astronomical Spectra
NEBULAE. AND. AGN. Introduction. We find in a wide variety of circumstances
warm and bright clouds of gas whose defining characteristic is that a central

Chromatography: Fundamentals and applications of ...
The pulsed discharge generates high-energy (13.5- to 17.5-eV) photons, which
photoionize a dopant gas (e.g., methane). The energy is sufficient to photoionize
all elements, except neon. The dopantacts as asourceofphotoelectrons, and in ...

Excited States in Organic Chemistry and Biochemistry
From this previous work it is reasonable to expect that under conditions of high
pH and low temperature thymine should photoionize from its excited tripled state.
ESR studies of the uv photolysis of thymine have shown that thymine does ...

Physics at the Laser-atomic Frontier
For example, radiation at 58.4 nm from a helium resonance lamp is often used to
photoionize materials by single photon absorption. The experiments required a
windowless discharge and the cumbersome technique of vacuum ultraviolet.

On the Formation of the Most Massive Stars in the Galaxy
Therefore, while stars with masses in the range M⋆ ∼ 5 to 15M ⊙ are not able to
photoionize enough hydrogen to detectable levels,3 stars with M⋆ roughly
greater than 15M ⊙ start to photoionize their own accretion flow [105]. It is to
these ...
