ON THE NATURE OF THE X-RAY-ABSORPTION IN THE SEYFERT-2 GALAXY NGC-4507

We present results of the ASCA observation of the Seyfert 2 galaxy NGC 4507. The 0.5-10 keV spectrum is rather complex and consists of sever al components: (i) a hard X-ray power law heavily absorbed by a column density of about 3 x 10(23) cm(-2), (ii) a narrow Fe K alpha line at 6.4 keV, () soft continuum emission well above the extrapolation of th e absorbed hard power law and (iv) a narrow emission line at similar t o 0.9 keV. The line energy, consistent with highly ionized neon (Ne IX ), may indicate that the soft X-ray emission is derived from a combina tion of resonant scattering and fluorescence in a photoionized gas. So me contribution to the soft X-ray spectrum from thermal emission, as a blend of Fe L lines, by a starburst component in the host galaxy cann ot be ruled out with the present data.
