dc.descriptionResults of an ASCA X-ray observation of NGC 4507 are presented. The spectrum is best parameterized by a double power law (or a partial covering) model plus a narrow FeK$α$ emission line likely due to the line-of-sight absorption matter. The data require also an emission line at $\sim$ 0.9 keV consistent with NeIX, which may indicate that the soft X-ray emission derives from a combination of resonant scattering and fluorescence of the radiation by photoionized gas. Moreover, complex absorption (or other, unresolved, emission lines) is required by the data below 3 keV. Similarities between the X-ray spectra of NGC 4507 and NGC 4151 are also stressed.
