- Abstract
We discuss the importance of the three-nucleon isospin component in elastic neutron-deuteron scattering and in the deuteron breakup reaction. The contribution of this amplitude originates from charge-independence breaking of the nucleon-nucleon potential. We study the magnitude of that contribution to the elastic scattering and breakup observables, taking the Av18 nucleon-nucleon potential alone or combined with the Urbana IX three-nucleon force as well as the locally regularized chiral N4LO nucleon-nucleon potential alone or supplemented by the chiral N2LO three-nucleon force. We find that the isospin component is important for the breakup reaction and the proper treatment of charge-independence breaking in this case requires the inclusion of the state with isospin . For neutron-deuteron elastic scattering the contributions are insignificant and charge-independence breaking can be accounted for by neglecting component and using the effective t-matrix generated with the so-called rule.
