Abstract In the limit of unbroken SU(3) symmetry, we exhibit a selection rule which forbids the decay of certain hypernuclear states involving a coherent admixture of ..lambda.. and ..sigma.. hyperons. This may provide an explanation of the narrow widths of some hypernuclear excitations observed in the ..sigma.. continuum.
