Effect of Δ-Isobar Excitation on Spin-Dependent Observables of Elastic Nucleon-Deuteron Scattering
Δ-isobar excitation in the nuclear medium yields an effective three- nucleon force. A coupled-channel formulation with Δ-isobar excitation developed previously is used. The three-particle scattering equations are solved by a separable expansion of the two-baryon transition matrix for elastic nucleon-deuteron scattering. The effect of Δ-isobar excitation on the spin-dependent observables is studied at energies above 50 MeV nucleon lab energy.
