Computations of scattering lengths in nnpp system within cluster reduction method for Yakubovsky equations

Abstract

Scattering lengths for d-d, n-${}^3$He and p-${}^3$H systems are computed via Cluster Reduction Method for Yakubovsky equations in configuration space taking into account Coulomb interaction between protons. MT I-III potential model was used to describe the nucleon-nucleon interaction. Results of calculations are in a good agreement with existing experimental data and results of calculations of other authors.
