Study of the reaction tp→ppnn at 2.5 GeV/c triton momentum

The liquid hydrogen bubble chamber technic was used to study the tp→ppnn reaction in 4π-geometry at the 2.5 GeV/c tritium nucleus momentum. The main characteristics of the reaction are described reasonably enough by pole dominance approximation in the absolute normalization and without free parameters. An incoherent sum of five diagrams was taken into account in the framework of this model. Numerical solution of the reaction cross section in the absolute normalization with the relativistic phase space were made by means of the Monte-Carlo simulation. In the framework of the model the cross section turned out to be equal to 32 mb and the experimental one was equal to 38.6+-1.6 mb
