Abstract
Pseudoscalar meson charge radii calculated in the PCAC soft-current limit approximation at the triangle level are in good agreement with the data. The authors study whether or not the removal of the soft-current limit improves the comparison between theory and experiment. No clear conclusion can be drawn as yet, but a slight improvement in the data will decide the issue.Keywords
