Collisional excitation of C+(2P) spin-orbit levels by molecular hydrogen revisited

Autor: Paul J. Dagdigian, Jacek Kłos, François Lique

Publikováno v: Monthly Notices of the Royal Astronomical Society: Letters

Relaxation of the spin-orbit excited C+(2P3/2) ion by collisions with H2 is an important process in the interstellar medium. Previous calculations of rate coefficients for this process employed potential energies computed for only collinear and perpe
