    "abstract": "Finite size effects in the equilibrium phase space density distribution\nfunction are taken into account for alculations of the relaxation of collective\nmotion in finite nuclei. Memory effects in the collision integral and the\ndiffusivity and the quantum oscillations of the equilibrium distribution\nfunction in momentum space are considered. It is shown that a smooth diffuse\n(Fermi-type) equilibrium distribution function leads to a spurious contribution\nto the relaxation time. The residual quantum oscillations of the equilibrium\ndistribution function eliminates the spurious contribution. It ensures the\ndisappearance of the gain and loss terms in the collision integral in the\nground state of the system and strongly reduces the internal collisional width\nof the isoscalar giant quadrupole resonances.",
