Variation with baryon density n_B of the average (solid lines) and most probable (dashed lines) values of the charge number Z (blue lines), cluster mass number A (orange lines), and total mass number A_cell (red lines) in the inner crust at two selected temperatures: T = 10¹⁰ K (panel a), and T = T_m (panel b). Results obtained in the one-component plasma (OCP) approximation are also shown (dotted lines).
