Manifestation of the bound state NN (1870) in the annihilation process pd→ps5π.

It is shown that the existence of an NN bound state with a mass of approximately 1870 MeV and width 10 MeV follows from analy- sis of the experimental data on the momentum distribution of recoil protons in the annihilation process pd→ps5π. © 1996 American Institute of Physics. [ABSTRACT FROM AUTHOR]
