“…From our analysis above (reactions (10), (10a) and (10b)), we suggested reaction (12) should be endothermic by 4.0 ± 3.7 kcal/mol provided D 0 (Ag + -Ag) is about 36 kcal/mol. This is very good agreement and strongly supports the experimental value of Beutel et al [48] for D 0 (Ag + -Ag) and suggests the value of Kruckeburg et al [49] of 40.1 ± 2.0 kcal/mol is slightly high.…”

“…As noted, a complete discussion of these bond energies will be presented elsewhere [45]. Literature values for loss of a neutral Ag atom from both Ag 2 + and Ag 3 + are available: 36.2 ± 0.7 kcal/mol [48] and 40.1 ± 2.0 kcal/mol [49] for Ag 2 + and 62.3 ± 3.2 kcal/mol [49] for Ag 3 + . Rate constants for the dissociation of Ag 2 + (Eq.…”

“…Hence, if D 0 (Ag + -Ag) < 39.2 kcal/mol, then reaction (9) is exothermic and simple thermochemistry could explain our experimental observation. There are two experimental values for D 0 (Ag + -Ag); Beutel et al [48], using photoionization of a cold Ag 2 molecular beam, obtained a value of 36.2 ± 0.7 kcal/mol. Kruckeburg et al [49] obtained a value of 40.1 ± 2.0 kcal/mol using multiple-collision induced dissociation in a Penning trap.…”

The emission of neutral and positively charged silver clusters during sputtering of a polycrystalline silver target by 5 keV Ar + ion bombardment has been studied and the sputter ejected silver flux has been characterized. As a result, the silver flux is found to be strongly dominated by neutral clusters rather than cluster ions. The contribution of neutral clusters in the overall silver flux decreases rapidly and monotonically with increasing cluster size n and decreases, in addition, with decreasing bombarding energy. The well known alternation of the secondary ion intensities of Agn + as a function of cluster size (higher intensities for odd n) is found to be correlated with the effective "ionization potentials" of the corresponding sputtered neutral clusters.

“…Among transition metal clusters, silver clusters have received considerable attention from both experimentalists [18,19,[21][22][23][24][25][26][27][28][29] and theoreticians [31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46]. In terms of electronic structure, transition metal clusters are more complicated than alkali metal clusters because of the presence of d electrons.…”

Ab initio Molecular Dynamics (MD) method, based on density functional theory (DFT) with planewaves and pseudopotentials, was used to study the stability and internal motion in silver cluster Agn, with n = 4−6. Calculations on the neutral, cationic and anionic silver dimer Ag2 show that the bond distance and vibrational frequency calculated by DFT are of good quality. Simulations of Ag4, Ag5, and Ag6 in canonical ensemble reveal distinct characteristics and isomerization paths for each cluster. At a temperature of 800 K, an Ag4 has no definite structure due to internal motion, while for Ag5 and Ag6 the clusters maintain the planar structure, with atomic rearrangement observed for Ag5 but not for Ag6. At a temperature of 200 K, Ag4 can exist in two planar structures whilst Ag5 is found to be stable only in the planar form. In contrast Ag6 is stable in both planar trigonal and 3D pentagonal structures. Microcanonical MD simulation was performed for all three clusters to obtain the vibrational density of states (DOS).
