Abstract: 
Recently Gell-Mann1 has proposed a new theory of the interaction between elementary particles. In this theory all baryons have spin ½, and the same mechanical mass and parity. They form a supermultiplet which is split up only when moderately-strong interactions occur by way of K mesons. The Hamiltonian of the interaction with π mesons is written in the following ways:
