摘要：
A novel method is presented for implementation of the extended mean-field theory incorporating two-body collisions. At a given time, stochastic imaginary time propagation of occupied states is used to generate a convenient basis. The quantal collision terms, including memory effects, are then computed by a backward mean-field propagation of these single-particle states. The method is illustrated in an exactly solvable model. Whereas the usual TDHF fails to reproduce the long time evolution, a good agreement is found between the extended TDHF and the exact solution. (C) 1999 Elsevier Science B.V. All rights reserved.
