Abstract

We present results of phase shift for I=2 $S$ -wave $\pi\pi$ system with the Wilson fermions in the quenched approximation. The finite size method proposed by L\"uscher is employed, and calculations are carried out at $\beta=5.9$ ( $a^{-1}=1.934(16)$ GeV from $m_\rho$ ) on $24^3 \times 60$ , $32^3 \times 60$ , and $48^3 \times 60$ lattices.
