Abstract It is shown that in the 9q- and 12q-systems, i.e.,3He-3He and4He nuclei, the most energetically favourable colour magnetic types of symmetry are [f]cs=[621] and [f]cs=[822], which corresponds to the orbital configurationsS 5 P 4 [522] X andS 6 P 6 [623] X . The colour magnetic nucleon attraction associated with these configurations increases as the square of the nucleon number in the sequence2H,3He,4He, becoming quite strong in4He. This may provide a basis for explaining the “mysterious properties” of3He-3He and4He. However, with the further increase in A, the above effect drastically decreases. A qualitative calculation on the quark excitation spectrum for the3H-3He and4He nuclei is presented. The4He nucleus seems to possess some properties of a “quark magic nucleus”. The experimental situation is discussed.
