Аннотация: A modification of the multicluster dynamic model with Pauli projection (MDMP) developed earlier for light nuclei is proposed. The modification consists in performing a total antisymmetrization of the MDMP wave functions over all nucleons using a technique worked out for this purpose. The formal and physical consequences of the antisymmetrization procedure, namely, the changes in the structure of the nuclear wave functions, the exchange effects in the electromagnetic and weak processes on six-nucleon (i.e. He-6 and Li-6) nuclei, etc. are studied in detail. The exchange effects were shown to give the decisive contribution to the magnetic form factors at moderate and high momentum transfers. The general classification of the operators is carried out allowing one to determine before calculations the observables in which the exchange effects should be important and in which one can use the initial multicluster wave functions without their explicit antisymmetrization. The developed model (AMDMP) makes it possible to reproduce successfully a large array of diverse experimental data on six-nucleon nuclei. The problem of the Li-6 quadrupole moment is also discussed.
