  We present the X-ray spectra of 86 optically-identified sources in the 13H
XMM-Newton/Chandra deep field which have >70 X-ray counts. The sample consists
of 50 broad line AGN, 25 narrow emission line galaxies, 6 absorption line
galaxies, and 5 Galactic stars. The majority (42/50) of the broad line AGN have
X-ray spectra which are consistent with a power law shape. They have a mean
photon index of Gamma = 2.0 +- 0.1 and an intrinsic dispersion sigma = 0.4 +-
0.1. Five BLAGN show a deficit of soft X-rays, indicating absorption.
Significant absorption is more common in the narrow emission line galaxies
(13/25) and absorption line galaxies (2/6) than in the broad line AGN (5/50),
but is not universal in any of these classes of object. The majority of the 20
absorbed sources have X-ray spectra consistent with a simple cold photoelectric
absorber, but 6/20 require more complex models with either an additional
component of soft X-ray emitting plasma, or an ionised absorber. Of the 16
galaxies which do not show evidence for X-ray absorption, only 2 objects are
likely to be powered by star formation, and both have 2-10 keV X-ray
luminosities of <= 10^40 cgs. The X-ray emission in the other 14 unabsorbed
NELGs and galaxies is most likely powered by AGN, which are not detected in the
optical because they are outshone by their luminous host galaxies. The Galactic
stars show multi-temperature thermal spectra which peak between 0.5 and 1 keV.
Star/AGN discrimination is possible for 4 of the 5 stars solely from their
X-ray spectra.
