Abstract
We present results for I=2 pion scattering length with the Wilson fermions in the quenched approximation. The finite size method presented by Lüscher is employed, and calculations are carried out at , 6.1, and 6.3. In the continuum limit, we obtain a result in reasonable agreement with the experimental value.
