摘要：

We report a value of -[3.3 +/- 1.1 (stat) +/- 0.7(syst)] x 10(-3) for the quadratic slope parameter h in the Dalitz plot of the K(L) --> 3-pi-0 decay. This result is obtained from a sample of 5.1 X 10(6) decays. The validity of the DELTA-I = 1/2 rule in the quadratic term is investigated using this result. This is the first measurement of the 3-pi-0 slope parameter, and also the most sensitive measurement of any of the quadratic slope parameters for the charged or neutral kaons.
