The dynamics of atomic nuclei is amongst the most challenging problem to treat theoretically. The richness of phenomena occurring in heavy-ion collisions can only be studied within microscopic approaches where each nucleon is treated quantum mechanically. Our goal is to present recent advances on microscopic descriptions of low energy heavy-ion collisions. We present both formal aspects and practical applications of the time-dependent Hartree-Fock (TDHF) theory, giving a mean-i¬?eld dynamics of the system. As an example, we study the fusion of nuclei and some competing processes. The TDHF theory has some intrinsic limitations: absence of tunneling below the Coulomb barrier, missing dissipative ei¬?ects and quantum i¬?uctuations. Mean-i¬?eld theories should be improvedto properly account for these ei¬?ects. Several approaches are presented which account for pairing and/or direct nucleon-nucleon collisions. Finally, we discuss recent progresses in exact ab-initio ...Похожие книги
