N2 - We present new corrections for the polarization-dependent efficiency (PDE), which introduces a false asymmetry into measurements of n-p analyzing power Ay(θ) caused by double scattering in the neutron side detectors. To accomplish this, we created a new database of C12(n-,n) Ay(θ) by using a combination of fits to data, phase-shift analysis, and R-matrix analysis. Our recorrection for PDE of previously reported n-p Ay(θ) data at 7.6 and 12.0MeV and new data at 7.6MeV indicate that we have achieved a superior representation of C12(n-,n). Our results continue to suggest a possible charge dependence of the pion-nucleon coupling constant.
