Ion recombination

CHXNH. Many of the reactions involve radiative association. Dissociative electron-ion recombination then yields neutrals such as CH (methane), C2H OH (ethanol) and CH CN (acetonitrile) [158]. It is often joked... 

In Sec. 8 we took the point of view that, when a molecule has been dissociated into ions, energy equivalent to the work done may be regarded as stored in the form of potential energy, which will be liberated when the ions recombine. The same point of view can be adopted with regard to the quantities Yvae and Y. The electrostatic part of this energy may be regarded as associated with the ionic field. 

I is the number of ions created per unit volume and time. The value used was / = 1.4 X 1010 ions cc.-1 sec.-1 which corresponds to irradiation with a 50-mc. source (see section on intensity of irradiation above) n is the number of ions per cc. Ion recombination coefficient... 

In deriving the kinetic equation describing the arrival of various ionic species at the cathode, it is assumed that the primary species N2 + is formed at the central wire at a constant rate, and during its passage in the direction x perpendicular to the axis its concentration is modified by various reactions. In this treatment both ion diffusion and ion-ion or electron-ion recombination processes are neglected because the geometry of the discharge tube and the presence of an electric field would... 

The simulation of an electronegative gas discharge converges much more slowly than that of an electropositive discharge. This is mainly caused by tbe slow evolution of the negative-ion density, which depends only on attachment (to create negative ions) and ion-ion recombination (to annihilate negative ions), both processes with a very small cross section. In addition to the common procedures adopted in the literature [222, 223, 272, 273], such as the null collision method, and different superparticle sizes and time steps for different types of particle, two other procedures were used to speed up the calculation [224]. 

Normally an electron beam is invisible to the human eye. However, when the electromagnetic tube contains a low-pressure gas that ionizes upon collision with an electron (emitting light when the ion recombines), the path of the electron beam can be seen.
