The muon neutrino-antineutrino flux ratios, viz., νμ/νμ generated from the decays of charged pions and kaons in atmosphere have been derived from the latest primary spectrum and the CERN ISR pp-collision data modified for p-nucleus interactions. The dynamical method of Allkofer et al. (1978) has been used in the present investigation. The estimated result for νμ/νμ yields 1.39 and 1.70 as E→0 and ∞, respectively. The neutrino fluxes from pion- and kaon-decay spectra have been calculated. Attention has been paid on prompt neutrino spectrum calculation from the decays of D mesons. A rough estimate on the prompt muon spectrum has been given. The calculated results have been compared with the previous available results.
