Nuclear collective motion in time-dependent density-matrix theory
Description
An extended version of the time-dependent Hartree-Fock theory, known as the time-dependent density-matrix theory (TDDM), is presented. It is pointed out that TDDM has a close relation with pairing theories such as the Hartree-Fock-Bogoliubov theory and the quasiparticle random phase approximation. TDDM is applied to the ground states and quadrupole states of 20O and 22O. The obtained results are compared with those obtained from the pairing theories. (author)
