摘要：

We present results for the I = 2 pion scattering length calculated using staggered fermions in the quenched approximation. The calculation uses the finite-volume dependence of the energy of a two-pion state. We find good agreement with current algebra predictions for scattering of Goldstone pions, and reasonable agreement for the non-Goldstone pions.
