Reduced rate coefficients Dif for the excitation and de-excitation processes in Al(4p) + H collisions as a function of the electronic bound energy Ef of the final states for the temperature T = 6000 K. The initial bound energy for Al(4p) is Ei = −1.90 eV. The bound energies are measured from the atomic ionization limit. The solid line shows the calculation using the simplified model; symbols show the full quantum calculation (Belyaev 2013a,b).
