文摘The quadrupole excitations in nucleus 11Li have been studied within the nuclear Vlasov equation approach.The classical phase space distribution function is given by the test particle propagation method.A soft mode of quadrupole excitation located around 2MeV is found.The total percentage of E2 energy-weighted sum rule exhausted in this soft resonance region is very sensitive to the extension of neutron halo in nucleus 11Li.The results compared with other recent calculations are analyzed.
