Description
Summary:The interpretation is given on the effect of two "peaks" appearance in the experimental deuteron energy distributions in the ⁴He(g, pn)²H reaction with photon energies Eg=30...50 MeV. The mechanism of pole ²H-diagram determining the first "peak" motion and the mechanism of triangular ³He(³H)-diagrams showing a fixed appearance of the second "peak" with a deuteron energy Em₂H=2.22 MeV due to the root singularity in the p + n → ²H vertex are taken into account. The position of maxima in the calculated distributions by the relative pn-pair energy, going out from the photon vertex, coincides in the diagrams under consideration for Eg=45...150 MeV.
