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. 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 possibly a charmonium once it is confirmed above the threshold by experiment.
