Figure 5. "Intrinsic" components of the vertical ionization potentials for cold Na_x [43], Cu_n [7,12,36] and Ag_n (this study). Tabulated numbers correspond to IP-WF-½e2/(R+a). Polycrystalline work functions were taken from reference [36], while element-specific spillout corrections are from reference [33]. Note the high degree of correspondence between data sets.
