electron attachment

The results indicate a competition between water and isopropanol for a secondary species resulting from electron attachment to N2O.

From this comparison, the electron attachment scheme proposed for the dense gas phase was extended to the liquid phase.

This reduction in yield appears to be due to electron attachment by the sulfur thereby suppressing formation of hydrogen from dissociative neutralization.

With James S. Allen, Rossi found gas mixtures of high electron mobility and low electron attachment.

The constant rate of vibrational excitation and dissociative electron attachment are more favorable for HCl than for other chlorine donors.

The insulator properties of the gas are controlled by the combination of electron attachment, electron scattering, and electron ionization.

The cross-section for electron attachment is inversely proportional to electron energy at high energies, but approaches a maximum limiting value at zero energy.

Experiments on electron attachment are yielding unique information on the dynamical polarisability of small clusters (see figure), and are confirming the predictions of the jellium model.

These studies will then be extended to pioneering studies of electron attachment to bio-molecules and to targets consisting of a bio-molecule clustered either with water or simple organic molecules.

Both reactions `convert' ferrous iron to hydroxyl radicals, and involve dissociative electron attachment to oxidants, H2O2 and HOCl respectively.

This work is supported by laboratory studies using spectroscopic methods for plasma diagnostics, computer modelling of the chemistry, and studies of electron attachment to molecules and free radicals.

Photodetachment/electron attachment spectroscopy The species which will be used in the formation of the fast neutral beams are, by necessity, either stable ground state or metastable (long-lived) excited state negative ions.

The low-pressure chemical ionization and electron swarm techniques were used to determine the density effect of the environment in the case of electron attachment to four linear or cyclic, primary or substituted amides:

Dissociative electron attachment to many stable molecules has been studied previously, but no such investigation of fragmentation following electron attachment to unstable molecular radicals such as OH has been pursued.

This reaction, also known as "electron attachment" or "dissociative electron attachment" is most likely to occur after the electron has essentially slowed to a halt, since it is easiest to capture at that point.

Extensive multireference CI calculations using a contracted 6s5p3d1f Gaussian basis set on the B and N atoms indicate that the X2∑+, A2Π, and B2∑+ states of BN− are bound with respect to the electron attachment BN + e−.

The negative ion profiles show moderately unsaturated hydrocarbon ions upstream formed by proton transfer followed by progressive dehydrogenation; the highly unsaturated, carbonaceous ions observed downstream appear to arise by two- and three-body electron attachment, charge transfer, and H-atom stripping.

He received his Bachelor of Arts (BA) degree in mathematics and physics with first class honors in 1935, and his Master of Arts (MA) degree in 1937, writing a thesis on "Electron attachment and negative ion formation in oxygen".

In addition, the low-energy electrons have a longer photoresist interaction time due to their lower speed; essentially the electron has to be at rest with respect to the molecule in order to react most strongly via dissociative electron attachment, where the electron comes to rest at the molecule, depositing all its kinetic energy.
