Abstract
We present results of phase shift for I = 2 S-wave ππ system with the Wilson fermions in the quenched approximation. The finite size method proposed by Lu¨scher is employed, and calculations are carried out atβ = 5.9 (a -1 = 1.934(16)GeV from m p ) on 24 3 × 60 , 32 3 × 0 , and 48 3 ×0 lattices.
