In order to compare with previous calculations we use a semiclassical approach based on the linearized Vlasov equation. Moreover, a quantum calculation is performed within the R.P.A.. The Coulomb effects are a slowing down of the growth and the occurrence of a minimal wave vector for the onset of the instabilities. The quantum corrections cause a further decrease of the growth rates.10 pages, revtex, 4 ps figures, to appear in Phys. Rev. C e-mail: gfabbri@fi.infn.it, matera@fi.infn.itNuclear Theorytext
