Configuration-Space-Faddeev Born Approximations
Alternative definitions of the Born approximation and the distorted-wave Born approximation within the framework of the configuration-space Faddeev equations are explored. The most natural definition does not correspond to the Born approximation derived from the Schrödinger equation, even though the exact T-matrices for both formalisms are equivalent. The Schrödinger form is optimal, although i...
متن کاملOperation of Faddeev-Kernel in Configuration Space
We present a practical method to solve Faddeev three-body equations at energies above three-body breakup threshold as integral equations in coordinate space. This is an extension of previously used method for bound states and scattering states below three-body breakup threshold energy. We show that breakup components in three-body reactions produce long-range effects on Faddeev integral kernels...
متن کاملFaddeev - Yakubovsky calculations for light ΛΛ hypernuclei
New Faddeev-Yakubovsky calculations are reported for 6 ΛΛ He and 10 ΛΛ Be in terms of clusters of α's and Λ's, using ΛΛ s-wave potentials motivated by several of the Nijmegen model interactions. The self consistency of the ΛΛ hypernuclear world data for these species is discussed. The newly reported 6 ΛΛ He event is found to be compatible with ΛΛ interaction strengths provided by the Nijmegen s...
متن کاملThree–Body Configuration Space Calculations with Hard Core Potentials
We present a mathematically rigorous method suitable for solving three-body bound state and scattering problems when the inter–particle interaction is of a hard–core nature. The proposed method is a variant of the Boundary Condition Model and it has been employed to calculate the binding energies for a system consisting of three 4He atoms. Two realistic He–He interactions of Aziz and collaborat...
متن کاملSolutions of Faddeev-Yakubovsky equations in configuration space for the 4N scattering states
The Faddeev-Yakubovsky equations in configuration space have been solved for the four nucleon system with special interest in their scattering states. We present results concerning the structure of the first He, scattering states in different (T,S) channels including the first inelatic threshold N+3N→NN+NN and the n-t cross section using realistic potentials.
