Provisional scheme for an interface installation of the moving line phenomenon. a A prelaunch stage. b The initial ML appearance, the start of hidden restructuring process. c A completion of stage 1 and the beginning t 1 of visible surface restructuring. d The finishing t 2 of the transitional stage and a starting of stage 2. e A final moment before vanishing of ML. f The last stage after ML disappearance. Denominations as MLE 0 and similar which connect with ML energy positions are true if the energy of valence level V is zero. Dotted lines indicate the virtual levels A s and V s in solid
