The e/h ratio of the ATLAS Hadronic Tile Calorimeter

We have determined the e/h ratios of the Module-0 of the ATLAS Tile iron-scintillator barrel hadron calorimeter for five values of pseudorapidity $\eta$ in the range of $-0.55 \le \eta \le -0.15$ for the beam energy range from 10 GeV to 300 GeV on the basis of the July 1999 test beam data. These $e/h$ ratios demonstrate independence from $|\eta|$ value. The mean value is $e/h = 1.362\pm 0.006$. The results are compared with the existing experimental data and with some Monte Carlo calculations
