Abstract
The static energy of the baryon number B = 2 SO(3) soliton calculated within the framework of the Chiral Quark Model is interpreted as a mas s of a dibaryon six quark state. The calculated mass is of the order o f 3 GeV and therefore dilambda lies above the physical threshold for t wo A decay. It is however argued that if the threshold itself is calcu lated within the same model dilambda mass is slightly below the mass o f two A. This is due to the fact that the chiral models overestimate t otal masses usually by a few hundred MeV.
