The motivation for the work reported is to improve the resonant charge transfer cross-sections to precision of experimental data of ion mobility in parent cases at weak electric field ~1%. We are particularly interested here with ions He, Ne, Ar, Kr, Xe, Rb, Cs, Hg.

Analytical expressions for cross sections as a function of relative energy are , in table are presented approximation parameters. Cross sections in unit 10-16 cm2, kinetic energy at eV, eV.
