The role of the excitation of the discrete spectrum is discussed. A comparison with electron scattering and muon capture data is presented. The cross section of electron neutrinos coming from muon decay at rest is calculated.6 pages, 5 eps figures, Presented at the XX Max Born Symposium, Wroclaw (Poland)Nuclear Theorytext
