Description
Comparison of the new data for the negative muon capture in 28^Si with the recent shell model calculations using a full 1s-0d model space and the USD empirical effective interaction and the one-nucleon weak current provides the induced pseudoscalar g_P substantially smaller than the value predicted by PCAC and pion-pole dominance. We find that adding the effect from the one-pion exchange axial charge density and using the same scheme of calculations does not change situation to the value of g_P.
