Description

Abstract A FORTRAN 77 program is presented that calculates the electromagnetic response of small metal particles or atomic clusters. The program uses the random phase approximation and the local density approximation, and treats the clusters as jellium spheres. From the frequency-dependence response the polarizability, the plasmon resonance frequency, and the width of the resonance lines are directly extracted. Title of program: JELLYRPA Catalogue Id: ABTC_v1_0 Nature of problem The electromagnetic response of small metal particles and atomic clusters is an object of current experimental interest. The electric polarizability and the plasmon resonance are measured, among other properties. The quantum mechanical theory of the response in the many- electron system is still not fully developed, but the Random Phase Approximation (RPA) in the Local Density Approximation (LDA) is simple and accurate enough to serve as a theoretical baseline for more elaborate treatments. The ...
