Description

We evaluate scattering lengths by use of a scattering amplitude calculated with the Bethe-Salpeter wave function inside the interaction range. Scattering lengths of I=2 two pions are computed by both conventional and our methods with $m_\pi = 0.52-0.86$ GeV in the quenched lattice QCD. The results are compared with each other to confirm consistency. Furthermore, a half off-shell amplitude is calculated.
