The reaction ppppη near the kinematical threshold is considered in the framework of the model, which includes the pp final states interaction (FSI). The Coulomb and strong effects of the pp FSI are calculated correctly in the model “Coulomb + Yamaguchi potential”. The pp FSI is shown to provide the main contribution to the energy dependence of the total cross section of the ppppη reaction close to threshold. The energy behavior of the total cross section is predicted in agreement with the data in the excess energy region < 15MeV. The predictions for different spectra are also performed.
