NUCLEAR EFFECTS IN NEUTRINO PRODUCTION OF DELTA AT INTERMEDIATE ENERGIES

The neutrino production of Delta in O-16 has been studied at intermedi ate energies relevant to atmospheric neutrino experiments. The Delta p roduction cross sections with electrons or muons in the final state is found to be reduced due to nuclear effects. This reduction is even la rger for the accompanying one pion production cross sections. The rati o of electron to muon production cross sections, however, does not sho w any significant dependence on nuclear medium effects. (C) 1998 Elsev ier Science B.V.
