Charge transfer cross sections and transport coefficients of 39K+ − 39K and 41K+ − 39K at low-energy

Abstract

The transport coefficients, diffusion D( T), and reduced mobility K0 are calculated for systems 39K+ − 39K and 41K+ − 39K in a thermal range between 1 and 3000 K within the Chapman–Enskog approximation. This is preceded by a theoretical study of the collision of alkaline ions in their gases for low and intermediate energies in the range 10−14 ≤ E ≤ 10−3 (a.u.), and within this field, we calculate the interaction energy potentials and elastic and charge-transfer cross sections and discuss the isotopic effects in the 39 K+ − 39K and 41K+ − 39K collisions.

Accurate Ab Initio Investigation of Electronic and Radiative Properties, and Cross Sections for Charged Diatomic Systems FrLi+ and FrNa+

“…The upper panel corresponds to the Fr + + Li(2s) collision, while the lower panel represents the Fr + + Na(3s) collision, with both systems in their ground state X 2 Σ + potential. Comparing our results with partial wave elastic scattering cross sections of other charged diatomic systems, − , we observe an identical behavior at low energy. This conformation can be attributed to the Wigner threshold law, which emerges from the analytic characteristics of the scattering wave functions during low-energy collisions.…”
