Antisymmetrization in the multicluster dynamical model of nuclei and nucleon-exchange effects

A modified version of the multicluster dynamical model of nuclei is propose d to construct completely antisymmetrized wave functions of multicluster sy stems. An overlap kernel operator is introduced to renormalize the total wa ve function after antisymmetrization with respect to nucleons belonging to different clusters. A group-theoretical method is developed to analyze the role of exchange effects that arise in calculating various observables of m ulticluster systems due to this antisymmetrization. The antisymmetrized ver sion of the multicluster dynamical model is applied to six-nucleon systems treated as alpha-2N ones. For six-nucleon systems, the static and dynamical characteristics that manifest themselves in electron and pi-meson scatteri ng, muon capture, beta decay, pion photoproduction, etc., are calculated. S ignificant advances are made in describing a variety of dynamical observabl es of six-nucleon systems in relation to the multicluster dynamical model. In the majority of cases, the calculated static and especially dynamical fe atures comply well with available experimental data.
