Low-energy multinucleon transfer reactions are shown to comprise a very effective tool for the production and spectroscopic study of light exotic nuclei. The corresponding cross sections are found to be significantly larger as compared with high-energy fragmentation reactions. Several optimal reactions for the production of extremely neutron-rich isotopes of elements with are proposed.
