  Some odd characteristics are observed in the single particle distributions
obtained from $ He + Li $ interactions at $ 4.5 AGeV/c $ momenta which are
explained as the manifestation of a new mechanism of strangeness production via
dibaryonic de-excitations. A signature of the formation of hadronic and
baryonic clusters is also reported. The di-pionic signals of the dibaryonic
orbital de-excitations are analyzed in the frame of the MIT - bag Model and a
Monte Carlo simulation.The role played by the dibaryonic resonances in
relativistic nuclear collisions could be a significant one.
  Key words: Relativistic nuclear interactions negative pions, negative kaons,
