摘　　要：The quark-delocalization colour-screening model is employed to study the kaonic nuclear cluster K-pp system. The calculation shows that there is a strong effective attraction between kaon and protons. The bound state can be formed and the binding energy is estimated to be about 80 MeV, and the space configuration is a symmetrical linear triatomic molecule with radius 1.15 fm. The results also show that the quark delocalization is responsible for the strong attraction in the system and the colour screening adds a little attraction in this case.The quark-delocalization colour-screening model is employed to study the kaonic nuclear cluster K-pp system.
