Description
We present the high-statistics analysis of axial charge and isovector form factor of nucleon in Nf=2 Wilson-clover fermion configurations. Using all-mode-averaging techniques at $m_\pi=190$--300 MeV in 2.5--4.0 fm lattice with three different lattice cut-off, we aim to compute these observables below 5% accuracy. In this poster we present preliminary study of rigorous calculation to search the region of ground-state nucleon dominance in which the excited state contamination is efficiently suppressed.
