Query: An irradiated accretion disk in the narrow-line Seyfert 1 RE J1034+396?   We model the optical to X-ray continuum spectrum of the narrow-line Seyfert 1
galaxy RE J1034+396. We show that the flat optical spectrum is consistent with
emission from an irradiated accretion disk. The X-ray emission can be modelled
with a disk blackbody and a Comptonised component. The temperature at the inner
edge of the disk T_{in} = (0.12 +/- 0.02) keV. Using this constraint, we show
that the flat optical spectrum is consistent with emission from the
irradiatively heated outer part of the accretion disk. We constrain the outer
radius of the optically thick disk (R >~ 5 x 10^{16} cm) and the inner radius
of the irradiation-dominated region (R >~ 5 x 10^{12} cm). Our optical and
X-ray spectral fits indicate a mass 0.6 <~ M <~ 3 x 10^6 M_{sun}, and do not
rule out a low (i.e. face-on) inclination angle for the system.
