Abstract
We report a value of -[3.3±1.1 (stat)±0.7(sys)]×10-3 for the quadratic slope parameter h in the Dalitz plot of the KL'30 decay. This result is obtained from a sample of 5.1×106 decays. The validity of the "I=1/2 rule in the quadratic term is investigated using this result. This is the first measurement of the 30 slope parameter, and also the most sensitive measurement of any of the quadratic slope parameters for the charged or neutral kaons. © 1992 The American Physical Society.
