Vi. Abrosimov et al., SEMICLASSICAL STRENGTH FUNCTION FOR ISOSCALAR VIBRATIONS OF THE NUCLEAR-SURFACE, Physics of atomic nuclei, 59(7), 1996, pp. 1130-1137
The isoscalar response of the surface of a Fermi-liquid drop of multip
ole orders L = 0, 2, and 3 is considered in the semiclassical approxim
ation based on the Vlasov kinetic equation. At L = 2 and 3, the distri
bution of oscillation strengths is found in the regions of giant nucle
ar resonances and low-lying collective states. At L = 3, this distribu
tion is also obtained in the region of a low-frequency octupole nuclea
r resonance.
