چکیده
We calculate the range corrections to S-wave neutron-deuteron scattering in the doublet channel (S = 1/2) to first order in r/a where a is the scattering length and r the effective range. Ultraviolet divergences appearing at this order can be absorbed into a redefinition of the leading order three-body force. The corrections to the elastic scattering amplitude below the deuteron breakup threshold are computed. Inclusion of the range corrections gives good agreement with measured scattering data and potential model calculations. Typeset using REVTEX [email protected] [email protected]

An approximate inverse scattering method [5, 6] has been used to construct separable potentials with the Laguerre form factors. As an application, we invert the phase shifts of proton-proton in the S0 and P2 − 3 F2 channels and neutron-proton in the S1 − 3 D1 channel elastic scattering. In the latter case the deuteron wave function of a realistic np potential was used as input.

We discuss a recent computation of Compton scattering on the deuteron at photon energies of order the pion mass. An interaction kernel is computed in baryon chiral perturbation theory and sewn to phenomenological deuteron wave functions. As an appetizer, we consider a computation of the pion-deuteron scattering length using this method.
متن کاملEffective Range in Doublet S-wave Neutron-Deuteron Scattering
The effective field theory approach is applied to the three-nucleon process of S = 1/2 neutron-deuteron scattering in the S-wave, including the effective range parameters summed at all orders. This is achieved through a modification of the power counting, following a recent suggestion in the literature. It is shown that with this procedure, while the convergence of the loop integrals improves, ...

Coulomb effects in the neutron-deuteron and proton-deuteron polarization-y are studied at energies above the deuteron breakup threshold. Theoretical predictions for these ob-servables are evaluated in the framework of the Kohn Variational Principle using correlated basis functions to expand the three-nucleon scattering wave function. The two-nucleon Argonne v 18 and the three-nucleon Urbana IX ...

Differential and total breakup cross sections as well as vector and tensor analyzing powers for p-d scattering are studied for energies above the deuteron breakup threshold up to E lab = 28 MeV. The p-d scattering wave function is expanded in terms of the correlated hyperspherical harmonic basis and the elastic S-matrix is obtained using the Kohn variational principle in its complex form. The e...
