Inelastic neutron scattering is used to measure the temperature dependence of the density of the Bose condensate in liquid helium. The character of the dependence coincides with the temperature dependence of the density of the superfluid component. The Bose-condensation temperature is T0 = Γλ. The relative density о the Bose condensate is ξ0 (ρ = О, Γ = 0) = 0.024 ±0.004.
