摘要

The spatial structure of the periphery of lithium and beryllium isotopes is studied by means of charge-exchange reactions and the (t, p) and (d, p) reactions on their nuclei. It is shown that the 0~+ isobaric-analog state of ~6Li at 3.56 MeV has a halo structure formed by a proton and a neutron, that there is virtually no manifestation of a neutron halo in the ground state of the ~9Li nucleus, and that the ~(11)Li nucleus has a Borromean halo structure that two neutrons form with respect to the ~9Li core and which manifests itself in cigar and dineutron configurations. The ~(10)Ве nucleus has a substantial two-neutron periphery in either configuration both in the ground and in the 2~+ excited state at 3.37MeV.
