25. The c(n√2 × √2)R45, where n = 9,7,5, and quasihexagonal structures would follow the c(2 × 2), successively, with increasing Li coverage on Ni(001) at 370 K, because these structures are formed at 230 K (see Refs. [18,22]).

27. The ratios of alkali-metal atoms' radii with respect to substrate atoms' radii are almost the same at 1.18, 1.27 and 1.21 for Li-Cu, Na-Ag and Li-Ni systems, respectively.
28. The reason why the (3 × 3) SAS is not formed for Li/Ni(001) can be understood by considering the change in the adsorption mode that occurs at a coverage in a range of 0.556 0.625.
