A precise determination of the neutron total cross section of 7Li and carbon has been made in the energy region 100 to 1500 keV. The parameters of the prominent 7Li resonance in the laboratory system are Eλ = 261 keV, Γλ = 36.5 keV and = 594 keV. Corresponding parameters for the principal bound state resonance in carbon are Eλ = −2020 keV and = 540 keV. The carbon data are fitted by σT = 4.830 − 3.55E + 1.587E2 − 0.305E3, where σT is in barns and E is in MeV. Above 500 keV the 7Li data are fitted by σT = 6.929 − 27.018E + 42.721E2 − 27.210E3 + 6.139E4.
