通过用扩展的Friedrichs方案描述，我们计算了t0和a波粲偶素态的衰变率，其中t0和a波粲偶素态为1或2，而t0和a波粲偶素态的衰变率则用Barnes-Swanson模型计算，其中t0和a波粲偶素态假定是通过中间态产生的。计算结果表明，t0的衰变率比t0小一个数量级，而t0、t1、t2的衰变宽度是同一数量级。
By describing theusing the extended Friedrichs scheme, in whichis considered as the dominant component, we calculate the decay rates of thetoand a-wave charmoniumstate with, 1, or 2, and the rate of its decay towith the help of the Barnes-Swanson model, whereare assumed to be produced via an intermediatestate. This calculation shows that the decay rate oftois 1 order of magnitude smaller than its decay rate toand the decay widths offor, 1, 2 are of the same order.
