| Abstract: | We make comments on [1], and provide partial wave analysis to the decays of excited heavy S-wave quarkonia into the basic quarkonia state plus . It is revealed that there exist contributions of D-wave transition in , and by using the data-fitting results in [1]. A possible experimental method to measure the D-wave directly is discussed.
