本文报道了电子偶素（）间隔的新测量结果。使用修改后的实验安排，我们已经显着减少了微波反射的影响，这在以前的实验中导致的移位和不对称的线的形状。用改进后的装置测得的实验值在理论值之内。
We report the results of a new measurement of the positronium() interval. Using a modified experimental arrangement we have significantly reduced the effects of microwave reflections, which in previous experiments resulted in shifts and asymmetric line shapes. With the improved apparatus we obtain an experimental value of, which is withinof the theoretical value.
