Od. Dalkarov et al., ON THE POSSIBLE MANIFESTATION OF THE (N)OVER-BARN(1870) BOUND-STATE IN (P)OVER-BARD-]P(S)5-PI PROCESS, Nuclear physics. A, 626(1-2), 1997, pp. 173-176
It is shown that the analysis of the experimental data on recoil proto
n momentum distribution from the annihilation (p) over bar d --> p(s)5
pi gives strong evidence for the bound (N) over bar N state with the
mass about 1870 MeV and the width about 10 MeV.
