Abstract

The potential energy surfaces for C�2(2Sþg) interacting with He, Ne and Ar are calculated usingab initioquantum chemistry methods. The PES are used to carry out coupled-channel quantum scattering cal-culations for the three systems to obtain the rotationally inelastic scattering cross sections from whichthe rotationally inelastic state-changing rate coefficients are computed. These rate coefficients are thenused to compute thermalisation times of C�2in an ion trap employing He, Ne or Ar as different, andpossible, buffer gases. A detailed analysis of their comparative collisional efficiencies is presented forguidance in trap modeling studies
