Zusammenfassung:The article contains general formulas for the production of J=3/2 resonances by neutrinos and antineutrinos. It specializes to the P{sub 33}(1232) resonance whose form factors are determined by theory and experiment and then are compared with experimental results at low and high energies. It is shown that the minimum in the low Q{sup 2} region is a consequence of a combined effect from the vanishing of the vector form factors, the muon mass and Pauli blocking. Several improvements for the future investigations are suggested.
