The deuteron momentum distribution ры(я) m the He nucleus has been determined, for the first time, from data on the reaction 4Hep-*pdd at an initial nuclear momentum of 2.7 GeV/c, for momenta q<0.3 GeV/c of the spectator deuterons. The experimental data were obtained with the help of the two-meter liquid-hydrogen bubble chamber of the Institute of Theoretical and Experimental Physics. The pole-dominance criteria are analyzed. An extrapolation of the nuclear vertex function to the pole yields a lower limit on the vertex constant, G2add= 5.97 ± 1.09 fm. The experimental data are compared with theoretical predictions.
