On the Interaction between Hyperons and Nucleons and the Hyperfragments

(Received September 27, 1955)
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 Λ0 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 Λ0 particle cannot be larger than 3/2.

In the text we have assumed that the cross sectios of the following two reactions are equal:
π-+d→n+n and π++d→p+p.
The latter cross section is given in the literature.
