Abstract (from CDS):

We present an observational study about the impacts of the interactions on the electron density of Hii regions located in seven systems of interacting galaxies. The data consist of long-slit spectra in the range 4400-7300Å, obtained with the Gemini Multi-Object Spectrograph at Gemini South (GMOS-S). The electron density was determined using the ratio of emission lines [Sii] λ6716/λ6731. Our results indicate that the electron density estimates obtained of Hii regions from our sample of interacting galaxies are systematically higher than those derived for isolated galaxies. The mean electron density values of interacting galaxies are in the range of Ne = 24-532/cm3, while those obtained for isolated galaxies are in the range of Ne = 40-137/cm3. Comparing the observed emission lines with predictions of photoionization models, we verified that almost all the Hii regions of the galaxies AM 1054A, AM 2058B and AM 2306B have emission lines excited by shock gas. For the remaining galaxies,
