26 Sep 2002 | | Journal: | Few Body Syst.Suppl. 14 (2003) 281-286 | | Subject: | nucl-th | | Affiliation: | Mainz, Germany | | Abstract: | The importance of three-body dynamics in the $eta np$ system in elastic and inelastic $eta$-deuteron scattering as well as coherent and incoherent $eta$ photoproduction on the deuteron in the energy region from threshold up to 30 MeV above has been investigated. It is shown that a restriction to first order rescattering with respect to the $NN$- and $eta N$-final state interactions, i.e., restriction to rescattering in the two-body subsystems, does not give a sufficiently accurate approximation to the s-wave reaction amplitude and that higher order terms, as described by the three-body dynamics give very substantial contributions. | | Source: | arXiv, nucl-th/0209085 | | Services: | Forum | Review | PDF | Favorites | |
