Phys. Rev. Lett. 74, 4993–4996 (1995)Exchange Current Corrections to Neutrino-Nucleus ScatteringReceived 28 September 1994; revised 2 February 1995; published in the issue dated 19 June 1995 Relativistic exchange current corrections to neutrino-nucleus cross sections are presented assuming nonvanishing strange quark form factors for the constituent nucleons. For charged current processes the exchange current corrections can lower the impulse approximation results by 10% while these corrections are found to be sensitive to both the nuclear density and the strange quark axial form factor of the nucleon for neutral current processes. Implications on the LSND experiment to determine this form factor are discussed. © 1995 The American Physical Society URL:
