  We present in this paper a list of candidates tidal dwarf galaxies selected
among a sample of 117 HII region observed in 11 minor mergers. The
classification of the HII regions was performed using the blue absolute
magnitude (M$_B$ $<$ -15), H$\alpha$ luminosity ($\cal L$$(H\alpha)$ $>$
10$^{39}$ erg s$^{-1}$) and the star formation rate ($SFR_{H\alpha}$ $>$ 0.4
M$_{\odot}$ y$^{-1}$) as parameters. The total number of UV photons, the number
of the star of each spectral type and the total stellar mass of the cluster
were computed for different models adopting Salpeter's IMF with $\alpha =
-2.65$ for the ionizing cluster. The ionizing cluster model which better
reproduce the observed properties are supermassive clusters with mass greater
than 10$^6 \leq M/M_{\odot} \leq 10^7$.
