摘要：
The results obtained from ASCA observations of the cluster of galaxies Abell 3627 are presented. This cluster, located behind the Milky Way, was recently found to be a nearby, X-ray bright, and very rich cluster. Pointed observations onto the central region of the cluster gave a gas temperature of similar to 7 keV and a metallicity of about 0.2 solar. An offset pointing to a substructure elongated to the south-east of the cluster center gave a significantly lower temperature of similar to 5 keV. The 2-10 keV luminosity within a radius of 40' (1.1 Mpc) is estimated to be 3.7 x 10(44) erg s(-1). The X-ray data imply a cluster mass of about 4 x 10(14) M-. within 40'.
