Abstract
The deuteron momentum distribution rho(dd)(q) in the He-4 nucleus has been determined, for the first time, from data on the reaction He-4p - -> 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 obtaine d 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 functio n to the pole yields a lower limit on the vertex constant, G(alphadd)2 = 5.97 +/- 1.09 fm. The experimental data are compared with theoretic al predictions.
