Cross-Sections and Transport Properties of F^-Ions in F₂

Abstract

We present the new results for the simple scattering cross-section set and proposed transport coecients for F − ions in F2 that can be used in such models. Nanbu's theory based on thermodynamic threshold energies and separating elastic and reactive collisions is used to calculate cross-sections for binary collisions of ions with atoms and molecules. Direct MC method is applied to obtain swarm parameters at temperature of T = 300 K.

Rate Coefficients of F-Ions in Ar/BF3Mixtures

“…Similar to our recent papers [10,11] Nanbu's theory is used to separate elastic from reactive endothermic * corresponding author; e-mail: zeljka@ipb.ac.rs collisions by accounting for the thermodynamic threshold energy and branching ratio according to the Rice RampspergerKassel (RRK) theory [5]. Within the RRK theory internal energy is being distributed among empirical number of s equivalent eective modes of the complex selected from the total number of atoms involved in the complex.…”

Reduced mobility of Ar+ in Ar/BF3mixtures

“…The knowledge of ion-neutral reactions is generally avaliable [4] although the effects of reactions on transport parameters of particular ions are much less studied due to non-detectability of rapidly vanishing ionic fluxes. This especially holds for ions whose transport is affected by fast reactions [5,6].…”
