%X Following the work of Bloch, the Thomas-Fermi model is extended to collective oscillations. The eigenfunctions and frequencies for radial and nonradial I = 1 modes are found. The calculated static polarization is compared with experiment, both for ions and neutral atoms, and the classical oscillator strengths are computed.
