Collective interatomic decay

Collective interatomic decay of multiple vacancies in clusters... 

Figure 6.6 Schematic representation of collective interatomic decay of two inner-shell vacancies, see Eq. (20).

Quantitative results for the collective interatomic decay in (4s-1,4s-1) (Kr+)2Ar have been obtained in Ref. [54] using Fano-ADC theory. The results for T as a function of the Kr-Kr distance (at R][ 2 Ar = 3.3A [54]) are shown in Figure 6.7a. At the equilibrium Kr-Kr distance (R = 4.0A [54]), the collective decay width reaches 1.9 meV for triplet and 2.0 meV for singlet doubly ionized states, which corresponds to lifetimes around 300 fs. The predicted lifetime is five orders of magnitude shorter than the one of the...
