DESCRIPTION: The convergent close-coupling method (CCC) is a non-relativistic formulation of the close coupling equations that solves for the scattering T-matrix in momentum space. The CCC database contains angle-integrated cross sections of electron scattering from atomic hydrogen H [1] and helium He [2] atoms and the molecular hydrogen ion H2+ [3]. For H and He the full set of cross sections (elastic, momentum-transfer, excitation, and ionization cross sections) are available for scattering from the ground state. The angle-differential cross sections and cross sections for scattering from excited states are available on request from the authors. For H2+ the CCC data base provides results from adiabatic-nuclei close-coupling calculations of hot (vibrationally excited) H2+. Collision data of H2+ and its isotopologues was obtained for scattering from each vibrational state of the electronic ground state and for the distribution of vibrational levels weighted according to the Frank-Condon (FC) factors. In the near future the CCC database will add comprehensive collision data of electron scattering from molecular hydrogen H2. Presently the database contains total cross section and cross sections for elastic scattering and ionization in the energy range from 0.1 to 300 eV and differential cross sections at 17.5 eV for the first seven states of H2 [4].
