ROLE OF STRANGE QUARKS IN QUASI-ELASTIC NEUTRINO SCATTERING

Confirming our previous proposal, we show within a continuum random-ph ase approximation calculation that the ratio of proton-to-neutron neut rino-induced quasielastic yield is a sensitive way to determine the st range quark axial form factor of the nucleon. Particularly, we find th at the ratio is virtually independent of final state interactions (acc ounted for by a finite-range force derived from the Bonn meson-exchang e potential) and nuclear structure effects. We present the ratio calcu lated for the neutrino beam available in an experiment currently appro ved at LAMPF.
