Abstract The combined analysis of the final event set of data on neutrino interactions inside the detector, upward going stopping muons and horizontal muons recorded in the Fréjus experiment is presented. The absolute atmospheric neutrino spectra in the energy range $$320{\rm M}eV〈 E_{v_e }〈 30GeV$$ for electron neutrinos and $$320{\rm M}eV〈 E_{v_\mu }〈 30GeV$$ for muon neutrinos are determined. Based on the parameterization of Volkova for thev µ a spectral index of γ=2.66±0.05 is obtained from the ratio of horizontal muons over upward going stopping muons and from the measurement of the energy loss of horizontal muons inside the detector. The neutrino spectra are compared with various flux calculations. They do not show any evidence for neutrino oscillations in agreement with earlier analyses of the Fréjus data.
