Abstract: The quantum corrections to the Vlasov equation are analysed in the framework of the Wigner representation. The method is applied to multipole vibration of nuclei and subbarrier heavy ion collisions. Using micro- and macroscopic models we demonstrate that quantum terms result in coherence effects for dipole and quadrupole giant resonances. Anomalous behaviour of protons transfer probability due to the Fermi surface deformation is predicted.
