The reaction d+d→p+t and elastic deuteron-deuteron scattering at 51.5 Mev.

The elastic deuteron-deuteron scattering and the reactions d(d,p)t and d(d,He) n have been investigated at an incident deuteron energy of 51.5 MeV. Time-of-flight technique was used for the particle identification. The observed angular distributions for the ( d, p) and ( d, n) reaction are identical within the accuracy of the experimental data. The experimental results for the reaction d(d, p)t are compared with a theoretical prediction based on the application of a generalized separable potential model to the four nucleon systems. Information on the single deuteron break-up reaction d+d→d+p+n and on the double deuteron break-up reaction d+d→p+p+n+n is contained in the observed continuous proton and deuteron spectra. The double break-up seems to be contribute only with a rather small amount to the whole break-up cross section. [ABSTRACT FROM AUTHOR]
