| 摘 要： | The isospin-dependent quantum molecular dynamics(IDQMD) model is used to study the total reaction cross section σR，The energy-dependent Pauli volumes of neutrons and protons have been discussed and introduced into the IDQMD calculation to replace the widely used energy-independent Pauli volumes,The modified IDQMD calculation can reproduce the experimental σR well for both stable and exotic nuclei induced reactions.Comparisons of the calculated σR induced by 11Li with different initial density distributions have been performed.It is shown that the calculation by using the experimentally deduced density distribution with a long tail can fit the experimental excitation function better than that by using the Skyrme-Hartree-Fock calculated density without long tails,It is also found that σR at high energy is sensitive to the long tail of density distribution.
