Abstract: The Time Dependent Local Density Approximation (TDLDA) is modified to incorporate the Self-Interaction Correction (SIC) of Perdew and Zunger. It is then applied to study the static polarizabilities and photoabsorption cross sections of small, spherical, neutral metal particles with 8, 20, and 40 Sodium atoms.
