Electron-impact-induced excitation and dissociation processes between the excited triplet states a (3)Sigma(g)(+)-->d (3)Pi(u), c (3)Pi(u)-->h (3)Sigma(g)(+), and c (3)Pi(u)-->g (3)Sigma(g)(+) of molecular hydrogen are studied by using the impact-parameter method. The cross sections for nu(i)-nu(f) resolved vibronic transitions between states have been calculated in the energy range from threshold to 100 eV; their maxima being located in the region of 5-10 eV. A special treatment was required for the transition to the h (3)Sigma(g)(+) state, whose adiabatic potential-energy curve possesses a barrier at the internuclear distance of about 5a(0), sustaining three quasi-bound vibrational states with widths of 5.3x10(-12), 1.5x10(-3), and 42.0 cm(-1), respectively. The quasistationary character of these vibrational states is taken into account when calculating the c (3)Pi(u)-->h (3)Sigma(g)(+) excitation and dissociation cross sections. |
