The encodings for different baryons and mesons can be taken from the
PDG96 [1].
It should be mentioned that there are no encodings recommended by the PDG96 for
some of resonances: , , , , and , , , , which spins have been not experimentally
established. Their encodings can be taken from the PDG98 [2].
