New calculations are made for the prompt component of atmospheric leptons (muon neutrinos and muons from the decay of charmed particles) in the same hadron cascade model used to calculate the characteristics of atmospheric leptons from the decay of π- and K -mesons. Spectral zenith-angular distributions of prompt and (π, K ) leptons are obtained. Cross-energy intervals are found for which the contribution from prompt lepton fluxes is comparable to those of (π, K ) muons and neutrinos. It is shown that prompt neutrinos can be detected at energies much lower than the cross-energy.
