Axial charge density in the Δ T=1, 0^+\leftrightarrow 0^-, isovector transition in nuclei with A = 16
Analysis of data on the axial charge density with allowance for the exchange meson current yields gp /gA ~ 10 for the ratio of the induced pseudoscalar form factor gp to the axial for factory of the nucleon. This result eliminates the large discrepancy between the prediction of current algebra (gp/gA —7-8) and the nuclear-physics determination in the impulse approximation (gp /gA ~ 13-20).
