  Title: DOES THE ABUNDANCE GRADIENT EXIST IN NON-CD-TYPE COOL CLUSTERS OF GALAXIES ?    


Abstract:
 One of the most striking results on clusters of galaxies field obtained with ASCA is
 existance of metal abundance gradient in cool cD clusters. Its scale-length of the
 abundance gradient is about 100kpc, which is smilar to the typical size of cD. The
 result implies a relationship between cD and the abaundace gradient. On the other
 hand, the existance of abundance gradient in hot component extending over the
 cluster tells us there is no relationship between cD and the abundace gradient. The
 best way to solve the problem is to observe non-cD cluster. However, there has been
 no observation of non-cD cool clusters. Then, we propose two non-cD-type cool clusters of galaxies; A168.
