Popis:	The optical potential and semiclassical methods have been applied to the studies of radiative charge transfer in collisions of ground-state and metastable Ne2+ ions with neutral helium. Cross sections are presented with relative collision energies between 0.1 meV and 10 keV. For all transitions concerned, the cross sections display rich resonance structures in the low-energy region. From the calculated cross sections, rate coefficients are obtained with temperatures between 10 and 20 × 106 K and are found to be in agreement with available experimental data. The multireference single- and double-excitation configuration-interaction (MRD-CI) method was used to obtain the relevant adiabatic molecular potentials and dipole transition matrix elements.
