- Аннотация: The problem of the origin of the quadrupole deformation in the Li-6 ground state is investigated with allowance for the three-deuteron component of the Li-6 wave function. Two long-standing puzzles related to the tensor interaction in the Li-6 nucleus are known: that of an anomalous smallness of the Li-6 quadrupole moment (being negative, it is smaller in Magnitude than the Li-7 quadrupole mornent by a factor of 5) and that of all anomalous behavior of the terisor analyzing power T-2q in the scattering of polarized 'Li nuclei on various targets. It is shown that a large (in Magnitude) negative exchange contribution to the Li-7 quadrupole mornent from the three-deuteron configuration cancels almost completely the "direct" positive contribution due to the ad folding potential. As a result, the total quadrupole moment proves to be close to zero and highly sensitive to fine details of the tensor nucleon-nUcleon interaction in the He-4 nucleus and of its wave function.
