The drift velocity of electrons in pure hydrogen, in pure
deuterium, and in mixtures thereof, has been observed at low pressures
using the following pulse technique for these gases for the
Plane parallel electrodes of a known separation and immersed
in the gas to be studied are connected...
A configuration-interaction determination of wave
functions has been made for the ²S and ²P states of lithium,
and for the ¹S and ³S states of the lithium ion.
Two 1s, one 2s, one 3s, and two 2p functions served as
starting functions for all four states. Results of the
The energy distribution of electrons in Townsend discharges in
helium has been experimentally investigated in a direct fashion.
A discharge is initiated between parallel plates of a small cell
mounted at the center of a spherical retarding field energy analyzer.
The anode of the cell is perforated and some electrons...
A knowledge of the time rates for intermediate reactions
during the photolysis of nitrogen dioxide enables one to deduce the
possible intermediate reactions which are responsible. An experiment has been devised and constructed which will measure the time
rates for photochemical reactions occurring in ranges of one micro
In this work the electron energy distribution functions and the
anisotropic drift term of the velocity distribution functions in non-self-sustaining
(Townsend) discharges in argon were determined by
direct measurement for a range of E/N (electric field strength by
gas atom concentration) from 70 to 407 Townsends (Td). (One Td
The three-body heterogeneous and wall recombination coefficients for atomic oxygen were measured using an electron paramagnetic
resonance spectrometer to monitor the time dependence of the
atomic oxygen concentration. This measurement was made for a
pressure range of from .224 to 1.10 torr using pyrolysis of ozone as
a source of...
Bicyclist safety at urban intersections is a critical element for encouraging an increase in bicycle commuting. With bicycle injury and fatality rates rising due to collisions with vehicles at signalized intersections, increasing the safety of riders continues to be an important consideration when promoting this mode of transportation. Previous research...
