Receiver techniques and detectors for use at millimeter and submillimeter wavelengths, and excitation cross sections for argon II, krypton II, and neon II gas lasers
Radiation and gas retention ages of chondrites from mass spectrometry of helium, neon, and argon
Feasibility and design of helium-neon laser displacement transducer
Replotted data for elastic scattering of helium ions on neon and argon
Negative feedback for discharge current noise reduction in excited helium-neon laser
Calculation of lifetime and transition probability of p-excited states of neon, argon, and krypton
Measurement of spontaneous emission phase fluctation in helium, neon lasers
Aluminum cold cathodes for helium-neon gas laser discharge tubes, giving graphs of pressure and power output vs time
Reflectance variation of painted surface during solid propellant retrorocket firing on surface measured by helium-neon laser
Uv transitions radiative lifetimes of neon, identifying unclassified lines
Scattering of neon, argon and xenon from silver surfaces, discussing values of interatomic binding energy
Rectangular-bore tube improves population inversion obtained from upper and terminal laser states, resulting in a significant increase in unsaturated gain factor. Radial field produces efficient pumping of upper laser state. Narrow tube dimensions cause increased diffusion flow of neon is metastable states to tube walls.
Single-electron capture by carbon ions from helium, neon, and argon at energies below 40 keV
Helium-neon laser discharge with striation oscillations in relation to pressure and current
Optically thin gas surrounding X ray source, plotting electron temperature and ionization equilibrium of hydrogen, He, carbon, nitrogen, oxygen and neon
Portable instrument passes light from helium-neon laser at a wavelength of 3.39 microns through the atmosphere being monitored and measures attenuation of the laser beam. Since beam attenuation is due almost exclusively to absorption of radiation by hydrocarbons, a quantitative measure of their concentration is available.
Weight and power aspects of integrated life support system having either nitrogen, helium, or neon atmosphere
Projected Hartree-Fock wave function analysis of inelastic proton scattering from neon-20
