DISTANT CLUSTER WITH LOW TEMPERATURE
ABSTRACT
We propose to observe distant clusters of galaxies with low temperature. Our purpuses to observe such objects are thw followings. One is to detrmine the abundance of Silicon and Sulfur in distant cluster, since there is little data of alpha element abandance in distant cluster. Another is to strecth the kT-Lx relation of distant cluster into the low temperature side, since there is also little data of it.
