摘要	Using a finite-difference pseudopotential density-functional theory in real space and Langevin molecular dynamics annealing technique, we perform calculations to determine the ground-state structure of the silicon cluster Si-9. It is found that the ground-state structure of Si9 cluster is a distorted capped hexahedron shape with C-s symmetry. And then, we implement the linear response theory within the time-dependent local density-functional formalism (TDLDA) to calculate the corresponding optical absorption spectrum. The spectral feature may help to identify isomers and can be used for comparison against future experimental investigations.
