  An analysis of a ROSAT/PSPC observation of the galaxy cluster A2634 is
presented. The cluster has a luminosity of $7.9\pm0.1\times10^{43}$erg/s in the
ROSAT band (0.1-2.4 keV). The temperature profile decreases from about 3 keV in
the outer parts to 1.2 keV in the centre. Within a radius of 1.5 Mpc the gas
mass of the cluster is 0.51$\times 10^{14}\msol$ and the total mass amounts to
$4.1^{+2.6}_{-1.8}\times 10^{14}\msol$. The X-ray morphology shows two peculiar
features -- a strongly peaked emission in the centre and an excess emission in
the south-west. The central emission probably originates from a weak cooling
flow, the SW emission is possibly associated with higher density regions in
pressure equilibrium with the intra-cluster medium. This region of excess
emission is somewhat embraced by the wide-angle radio tails associated with
3C465 suggesting that the overpressure of the relativistic particles has
displaced the thermal gas.
