Abstract

A new theoretical approach to nuclear reactions which are accompanied by the decay of interacting subsystems through various channels is reviewed. Inthis approach, which has been developed in recent years and is called antisymmetrized molecular dynamics (AMD), nucleons are associated with wave packets (Brink orbitals) and the dynamic problem is reduced to those classicalequations for the wave packet centers which involve the antisymmetrizationeffects but ignore other quantum effects. The basic points of AMD are illustrated by the example of simple nuclear systems. The AMD results are compared with those obtained from exact quantum-mechanical description in Fock-Bargmann space, The field of AMD applicability including the discrete-spectrum states is discussed. The relation of the AMD classical trajectories and quantum distributions to the statistical-physics representation is found. Anew interpretation of the Brink orbitals and Slater determinants, which are constructed on these orbitals as eigenfunctions of the coordinate operator defined in the Fock-Bargmann space, is proposed.
