Abstract : A value of \( (-6.1\pm 0.9_{stat}\pm 0.5_{syst})\times 10^{-3} \) is obtained for the quadratic slope parameter \( h \) in the \( K_{L}\rightarrow 3\pi ^{0} \) decay Dalitz plot at the NA48 experiment at the CERN SPS. The result is based on \( 14.7\times 10^{6} \) fully reconstructed \( K_{L}\rightarrow 3\pi ^{0}\rightarrow 6\gamma \) decays. This is the most precise measurement of any of the Dalitz plot slope parameters in the charged and neutral kaon decays so far.
