We determine scattering phase shifts for S,P,D, and F partial wave channels
in two-nucleon systems using lattice QCD methods. We use a generalization of
Luscher's finite volume method to determine infinite volume phase shifts from a
set of finite volume ground- and excited-state energy levels on two volumes,
V=(3.4 fm)^3 and V=(4.5 fm)^3. The calculations are performed in the
SU(3)-flavor limit, corresponding to a pion mass of approximately 800 MeV. From
the energy dependence of the phase shifts we are able to extract scattering
parameters corresponding to an effective range expansion.Comment: 7 pages, 11 figures. Proceedings of the 33rd International Symposium
