We study the structure of states of the isobaric triplet of {ital A}=6 nuclei ({ital J}{sup {pi}}=0{sup +}) within the framework of the three-particle {alpha}+2{ital N} model. The method of hyperspherical harmonics is used. It is shown that the features of the shape of the correlation density {ital P}({ital r}{sub {ital NN}},{ital r}{sub {alpha}({ital NN})}) of these states can be explained by the dominance of the harmonics with {ital K}=2 in the problem. The main qualitative properties of the three-particle decay of the {sup 6}Be(0{sup +}) resonance are explained. It is argued that the single-particle density of the nuclei considered has a nonstandard shape characterized by two radii of the nucleon distribution.
