Sodium clusters abundance spectrum

FIG. 9. Sodium cluster abundance spectrum detected by Knight [64]... 

Figure Cl.1.2. (a) Mass spectrum of sodium clusters (Na ), = 4-75. The inset corresponds toN= 75-100. Note the more abundant clusters at 77= 8, 20, 40, 58, and 92. (b) Calculated relative electronic stability, A(N + 1) - A(AT) versus N using the spherical electron shell model. The closed shell orbitals are labelled, which correspond to the more abundant clusters observed in the mass spectrum.
