Mn II, Fe II, Ti II, Cr II and Cu II emission spectra from a Grimm-type glow discharge in neon were studied using the formalism of transition rate (TR) diagrams. Relative radiative depopulation rates of excited ionic levels of these elements were established, contributions from radiative decay of higher excited states (cascade excitation) were subtracted and the resulting net depopulation rates were plotted as function of energy of the levels involved. A common pattern in those diagrams was found, indicating that singly charged ions of these elements are created, in addition to other mechanisms, by charge transfer between doubly charged ions of the element under study and metastable neutral neon atoms.
