N-d scattering including electromagnetic forces

Abstract

The electromagnetic potential consisting in the Coulomb plus the magnetic moment interactions between two nucleons is studied in nucleon-deuteron scattering. For states in which the relative N-d angular momentum L has low values the three--nucleon problem has been solved using the correlated hyperspherical harmonic expansion basis. For states in which the angular momentum L has large values, explicit formulae for the nucleon-deuteron magnetic moment interaction are derived and used to calculate the corresponding T-matrices in Born approximation. Then, the transition matrices describing N-d elastic scattering have been derived including an infinite number of partial waves as required by the 1/r^3 behavior of the magnetic moment interaction. Appreciable effects are observed in the vector analyzing powers at low energies. The evolution of these effects by increasing the collision energy is examined.
