- Аннотация: A brief survey of experimental results on elastic deuteron-deuteron scattering is given. Data from an experiment performed at the Institute for Nuclear Research (National Academy of Sciences of Ukraine, Kiev) at E-c.m. = 23.4 and 25.0 MeV and data from the literature at E-c.m. = 11.6 MeV are used to analyze the reaction involving the flip of the spins and isospins of two dinucleons into a singlet, d + d --> d(s) + d(s) or (pp)(s) + (nn)(s). Two-dimensional coincidence spectra of protons from the reaction d + d --> p + p + n + n are simulated with allowance for dominant quasibinary processes, including quasifree proton scattering and final-state nucleon-nucleon interaction. It is concluded that this reaction is dominated by the mechanism involving double spin-isospin flip. The differential cross sections dsigma/dOmega for the reaction H-2(d, d(s))d(s) at E-c.m. = 23.4 MeV and the reaction H-2(d, (pp)(s))(nn)(s) at E-c.m. = 11.6 MeV are determined. The elastic-scattering cross sections and the cross sections for spin-flip reactions leading to the formation of a singlet ground state are compared with the results produced by the supermultiplet potential model where the interaction between clusters A and B is described by a potential V-[f] (R) ([f] is an orbital Young diagram). The theory faithfully reproduces experimental results, but data on the flip of the spins and isospins of two deuterons are scanty (it is desirable to supplement them).
