Time-dependent local density approximation calculations for absorption spectra of small sulfur clusters
J. Phys. B: At. Mol. Opt. Phys. 36 (2003) 4511-4517,-0001,():
Absorption spectra for small sulfur clusters Sn (n = 2-8) are calculated using an adiabatic time-dependent density-functional formalismwithin the local density approximation (LDA). We compare the calculated spectra with those calculated using the simple LDA approach. The calculated spectra exhibit a variety of features that can be used for comparison against future experimental investigations. In addition, we also obtain a significant threshold absorption, which can distinguish different ground states of the sulfur clusters.
