Deuteron Formation in Nuclear Matter within the Faddeev Approach
We consider deuteron formation in heavy ion collisions at intermediate energies. The elementary reaction rates (Nd → NNN etc.) in this context are calculated using rigorous Faddeev methods. To this end an in-medium Faddeev equation that consistently includes the energy shift and Pauli blocking effects has been derived and solved numerically. As a first application we have calculated the life-ti...
متن کاملDeuteron Formation in Heavy Ion Collisions within the Faddeev Approach
We address the formation of correlations in a general nonequilibrium situation. As an example we calculate the formation of light composite particles in a heavy ion collision. In particular we study the formation of deuterons via three-body reactions in some detail. To calculate the relevant reaction rates we solve the Faddeev equation which is consistently modified to include the self energy c...
متن کاملProjectable Multivariate Wavelets: Separable vs Nonseparable
Tensor product (separable) multivariate (bi)orthogonal wavelets have been widely used in many applications. On the other hand, non-tensor product (nonseparable) wavelets have been extensively argued in the literature to have many advantages over separable wavelets, for example, more freedom in design of nonseparable wavelets (such design is typically much more complicated and di±cult than the a...
متن کاملBethe–Salpeter Approach with the Separable Interaction for the Deuteron
Recent developments of the covariant Bethe–Salpeter (BS) approach with the use of the separable interaction for the deuteron are reviewed. It is shown that the BS formalism allows a covariant description of various electromagnetic reactions like the lepton-deuteron scattering, deuteron electro-disintegration, deep inelastic scattering (DIS) of leptons on light nuclei. The procedure of the const...
متن کاملLow Energy Proton-Deuteron Scattering with a Coulomb-Modified Faddeev Equation
A modified version of the Faddeev three-body equation to accommodate the Coulomb interaction, which was used in the study of three-nucleon bound states, is applied to the proton-deuteron scattering problem at energies below the three-body breakup threshold. A formal derivation of the equation in a time-independent scattering theory is given. Numerical results for phase shift parameters are pres...
