Based on the principle of charge independence and the experimentally established evidences for the existence of the hyperfragment ^3H, the nature of the force between a Λ^0 particle and a nucleon is investigated. It is shown that the range of the Λ-N force cannot be longer than half the pion Compton wave length and that its well depth parameter is larger than about 0.4. This result suggests us the possible existence of the so-called hyper di-nucleons. Next, the mechanism of the non-mesonic to decays of a hyperfragment ^4He is investigated. A qualitative argument leads to the conclusion that the spin of the Λ^0 particle cannot be larger than 3 / 2.
