The strong 
and transitions are analyzed via three-point QCD sum rules. First we calculate the corresponding strong coupling constants 
and 
. Then we use them to calculate the corresponding decay widths and branching ratios. Making use of the existing experimental data on the ratio of the decay width in the pseudoscalar 
channel to that of the vector 
channel, finally, we estimate the decay width and branching ratio of the strong 
transition.
