To understand the diamond growth mechanism in C2H2/O2 flame, we carried out gas analyses for various mixture ratios ($R{=}$C2H2/O2) with laser-induced fluorescence and mass spectrometric techniques. These measurements show that CO and H2 are the dominant gases in the feather, and that C2H2 and $C$-containing radicals (e.g., C2H, CR, Cn, $n{=}1\text{--}3$) are minor species. Their concentrations are found to be consistent with the equilibrium values estimated by the adiabatic calculation. The feather is formed by the inter-diffusion and reactions between these $C$-radicals and $O$-radicals (e.g., O and OH), which are produced in the intermediate zone by the oxidation with O2 supplied through the secondary flame. It is also found that $R$-dependences of the diamond growth rate is in good agreement with those of CH and C2 concentrations in the feather.
