    "abstract": "The pseudo scalar form factor, which represents the pseudo scalar quark\ndensity distribution due to finite quark masses on the nucleon, is shown to\nmanifest itself with the induced pseudo scalar form factor in the $L_0^+$\namplitude for the charged pion electro-production. Both form factors show their\nown peculiar momentum dependence. Under the approximation on which the\nGoldberg-Treimann relation holds, a sum of both form factors\u0027 contributions\naccounts for the t-channel contribution in the charged pion electro-production\nnear threshold.",
