Abstract
The strong decays of the radially excited state are studied within the model. As a believed , some strong decay widths and relevant ratios of are calculated in the model. The theoretical results are consistent with experiments. In a similar way, as a possible , the same strong decay widths and relevant ratios of are presented. Our study indicates that is hard to be identified with a charmonium once it is confirmed under the threshold, but it is very possibly a charmonium once it is confirmed above the threshold by experiment.
