NUCLEAR TESTS FOR THE STRANGE CHARGE FORM-FACTOR OF THE NUCLEON

It is shown that the measurements of elastic and inelastic scattering of neutrinos and parity-violating asymmetry of longitudinally polarized electrons on spin-isospin zero nuclei would yield model independent information about the strangeness charge form factor. Numerical estimates of the contribution of this form factor are presented for He-4, C-12 and O-16 nuclei in impulse approximation using strangeness vector form factors of the nucleon recently suggested in the literature. A general relation between the P-odd asymmetry in electron scattering and the cross sections of neutrino and unpolarized electron scattering on spin zero nuclei is obtained.
