The Response of Metal Clusters to q- and L- Dependent External Fields
We have calculated the static polarizability and mean excitation energy of metal clusters submitted toq-andL-dependent external fields of jL(qr)YL0(Ω) type. Use has been made of an Extended Random-Phase Approximation which includes exchange and correlation effects within a local model, and of the spherical jellium model to describe the neutralizing positive background.
