Abstract
The accuracy of the time-dependent local-density approximation (TDLDA) for group-IB elements is preserved under the additional approximation of using pseudopotentials to treat the effects of core electrons. This extends the work of Zangwill and Soven, who showed the utility of the all-electron TDLDA in the atomic response problem, and justifies using pseudopotentials in calculating the far-ultraviolet response of multiatom systems.Keywords
