Abstract：
A peculian cosmic ray double core event K5618 was recently found in Mt.Kanbala emulsion chamber,with the following characteristic quantities:zenith angle=27°,total visible energy ΣE_γ=547TeV;energies of the two cores E₁=428TeV and E₂=119TeV with the separation between them R₁₂=25.56cm.it is expected that such an event might give some indication of the signal of the production of extraordinarity large transverse momentum particles in super high energy hadronic interactions.
