Abstract

The matter, neutron, and proton radii of nucleon-stable 1+ and 0+ states of the 6Li nucleus are studied theoretically within the no-core shell model. The results have been comparatively analyzed with the radii of the 0+ state of the 6He nucleus. To increase the accuracy of calculations, we have developed an extrapolation procedure. A new definition of the quantitative measure has been proposed and justified to describe the properties of a halo formed by loosely bound neutrons and protons in the A-nucleon problem. The sizes of the halo in the indicated states of 6Li have been calculated for the first time. It has been demonstrated that the sizes of their halos are close to those of the two-neutron halo in 6He. Thus, additional reliable evidence of the existence of the neutron–proton halo in the discussed states of 6Li has been obtained.
