Ro-vibrational Charge Exchange Cross Sections in C $^{4+}$ and H$_{2}$ Scattering at Low Energies

We report the calculation for electron capture during C $^{4+}$ collisions with molecular hydrogen at low incident energies. Using the multi reference single- and double-excitation (MRD-CI) method [1] we calculate all adiabatic potential energy curves and the non-adiabatic coupling matrix elements. We use quantum close coupling method [2] to evaluate various excitation cross sections. Details will be presented at the meeting. [1] R. J. Buenker and S. D. Peyerimhoff, Thoer. Chim.
