Benchmark calculations for polarization observables in three-nucleon scattering
High precision benchmark calculations for phase shifts and mixing parameters as well as observables in elastic neutron-deuteron scattering below the deuteron breakup threshold are presented using a realistic nucleon-nucleon potential. Two totally different methods, one using a variational principle in configuration space and the other solving the Faddeev equations in momentum space, are used an...
متن کاملNucleon polarization in deuteron electrodisintegration.
Outgoing nucleon polarization in exclusive deuteron electrodisintegration is studied at the quasi-elastic peak in the standard theory with emphasis on the effect of nucleonic and pionic relativistic corrections. The cases of polarized beam or/and polarized target are considered. Sizeable relativistic effects are pointed out in several polarization components. The sensitivity of nucleon polariza...
متن کاملThree-Body Halo Fragmentation: Polarization effects
Momentum distributions of particles from nuclear break-up of fast three-body halos are calculated for polarized beam and outgoing fragments. These momentum distributions are combined in observable quantities which emphasize the two-body correlations in the initial three-body structure as well as in the final two-body system. Applying the formalism to Li we find a sensitive dependence on the p-w...

Just as 3 → He can be approximately characterized as a polarized neutron target, polarized 6 LiD has been advocated as a good isoscalar nuclear target for the extraction of the polarized gluon content of the nucleon. The original argument rests upon a presumed " alpha + deuteron " picture of 6 Li, with the polarization of the nucleus carried by the polarization of the deuteron. We have calculat...
متن کاملRealistic models of pion-exchange three-nucleon interactions
We present realistic models of pion-exchange three-nucleon interactions obtained by fitting the energies of all the 17 bound or narrow states of 3 ≤ A ≤ 8 nucleons, calculated with less than 2% error using the Green’s function Monte Carlo method. The models contain two-pion-exchange terms due to πN scattering in Sand P-waves, three-pion-exchange terms due to ring diagrams with one ∆ in the inte...
