We present a result of different types of galaxy clusters distinction according to their core gravitation field. Ota & Mitsuda (2002) found the histogram of the core radius shows two peaks by using the isothermal β-model. They suggested that clusters should be divided into at least two subgroups according to their core radius. This result was not found before and the origin is still unclear. We believe that the unique core distribution is related to the dynamical evolution stage of galaxy clusters. Therefore, we introduce a new character a[c], the core gravitation field, which proportional to βkT/r[c], instead of r[c] in the classification because a[c] contains more cluster properties. By applying this new character into Ota & Mitsuda's sample and previous cluster sample set, we show that a[c] can work on the classification of previous data but r[c] can not. From this result, we suggest that it might be more appropriate to use a[c] than r[c] to divide clusters into different subgroups.
