The capture of low-energy electron by closed-shell sodium clusters was studied using the TDLDA within the spherical jellium model and the classical scattering theory of Langevin. Capture cross sections were computed for Na20, Na40, and Na58 and compared with the predictions of the classical image charge model and recent experimental results. It was shown that in the range of impact energies considered, the TDLDA capture cross sections are always larger than the classical ones obtained by using the macroscopic image charge model.
