A combination of electron scattering and laser-induced fluorescence (LIF) techniques was used in the experimental determination of the absolute cross section for the formation of Si(1S) ground-state atoms following the neutral molecular dissociation

We measured absolute cross sections for the electron-impact ionization and dissociative ionization of the SF5 and SF3 free radicals from threshold to 200 eV using the fast-neutral-beam technique. The total single ionization cross sections at 70 eV we

The vacuum ultraviolet (VUV) emissions of the hydrogen Lyman series following the dissociative excitation of the Si-organic compounds tetraethoxysilane (TEOS), tetramethylsilane (TMS), and hexamethyldisiloxane (HMDSO) by controlled electron impact we

A three‐mesh gate is used in a time‐of‐flight (TOF) apparatus to analyze the velocity of positive ions. Test results and a theoretical description are presented of an effect arising from trapping ions between meshes of a two‐gate TOF velocity

Studies of spacecraft surfaces in LEO have shown that CN(B - X) emission occurs when the spacecraft shuttle engine exhaust species collide with the atmosphere. A study of the reaction of fast O(3P) atoms with HCN under single-collision conditions is

Theoretical considerations and test results are presented for a new‐type velocity analyzer for incident fast neutral particles, positive ions, and negative ions. Velocity analysis is carried out by means of a pulsed, three‐gate time‐of‐flight

Optical emission has been observed corresponding to vibrational bands in the NH (A 3Pi - X 3Sigma(-)) electronic transition during collisions of 5 eV, ground-state oxygen O(3P) atoms with MgF2 and Ni surfaces continuously exposed to a beam of hydrazi

Measurements have been conducted of the 300-850 nm recombination spectra associated with 5-eV collisions of O(3P) atoms with NO adsorbed on surfaces of MgF2, Ni, and Ti. Attention is given to the dependence of chemiluminescence intensity on surface t

We studied the emission of the fluorine (2p43s) 2,4P→(2p5) 2P resonance lines in the vacuum ultraviolet (VUV) at 95.5 and 97.5 nm, respectively, following dissociative excitation of SF6, CF4, NF3, and CCl2F2 by controlled electron impact under sing

The electron--polarized-photon coincidence technique has been used to study the finer details of the excitation of the first excited states of the heavy noble gases neon, argon, and krypton by electron impact in the regime of large impact parameters
