Research On Neutron Induced Nuclear Reaction And Symmetry Energy Based On Skyrme Interaction

With the radioactive beam facilities exists in the word, much nuclear reaction data can be reached now, which makes nuclear science develop into areas about higher energy. temperature, density, spin and isospin. we try to study nuclear symmetry energy via nucleon-nucleus collision under isospin physics.First, an review about nuclear reaction model and nuclear structure theory will be posed briefly, based on the connection between nuclear macroscopic parameters and Skyrme interaction, additional with simple formation and physically transparent Skyrme interaction, we choose Skyrme interaction, to study n+208Pb reaction, in order to constrain nuclear symmetry energy with nuclear reaction data. In order to get the explicit impression of nuclear macroscopic parameters on nuclear reaction data, we try to find the most and least dependence of nuclear reaction data on 10 macroscopic optical parameters [P0,Esym(P0),GV,K0,L,W0,m*s,0,E0,GS,m*v,0] in microscopic optic model based on Skyrme interaction by Q.B.Shen et al, then symmetry energy will be constrained.For an extensive study, we try to study asymmetric nuclear matter to get more explicit result, combined with Skyrme-Hartree-Fock approach.After the calculation in nuclear reaction data of asymmetric nuclear matter, we find that in 10 macroscopic parameters, nuclear reaction data shows large dependence on isoscalar effective mass and imcompressibility, medium dependence on symmetry energy at saturation density and spin-orbit coupling parameter,less dependence on binding energy per nucleon.
