    "abstract": "A polarization and response function for finite systems and temperatures is\nderived from linearizing the Vlasov equation. Besides the Lindhard response\nfunction in local density approximation we obtain an additional contribution\ndue to the surface. This formula is applied to isoscalar giant resonances which\nwe consider as next harmonics to the basic dipole mode. The spurious center of\nmass motion is subtracted within the polarization. The results based on simple\nFermi liquid considerations are in reasonable agreement with experimental data.",
