ASCA observations of massive medium-distant clusters of galaxies. II.

We have selected seven medium-distant clusters of galaxies (z similar to 0. 1-0.3) for multi-wavelength observations with the goal of investigating the ir dynamical state. Following Paper I (Pierre et al. 1999) which reported t he ASCA results about two of them, we present here the analysis of the ASCA observations of the other five clusters; RX J1023.8-2715 (A 3444), RX J103 1.6-2607, RX J1050.5-0236 (A 1111), RX J1203.2-2131 (A 1451), and RX J1314. 5-2517. Except for RX J1031.6, whose X-ray emission turned out to be domina ted by an AGN, the ASCA spectra are well fitted by a one-temperature thin t hermal plasma model. We compare the temperature-luminosity relation of our clusters with that of nearby ones (z <0.1). Two clusters, RX J1050.5 and RX J1023.8, show larger luminosities than the bulk of clusters at similar tem peratures, which suggests the presence of a cooling ow. The temperature vs. iron-abundance relationship of our sample is consistent with that of nearb y clusters.
