For application to spectroscopic seed fraction measurement in a closed-cycle MHD (magnetohydro-dynamics) power generation system, the relation between the total absorption of second resonance doublets and atomic number density was determined experimentally for K-He (potassium 5p-4s lines : 404.4, 404.7 nm) and Cs-Ar (cesium 7p-6s lines : 455.5, 459.3 nm) mixtures. Atomic number density of alkali metal was precisely measured by a modified hook method which is not affected by the profile and width of the absorption coefficient. The results were compared with the total absorption calculated using the previous experimental data on collision broadening and the applicability of these data to quantitative measurement of atomic number density was investigated.
