The 2 neutral-pion CP-violating decay of the neutral-K2-meson was studied in a recent experiment at the Princeton-Pennsylvania Accelerator. The energy spectrum of generated gamma-rays was obtained for the center-of-mass system of the neutral-K2 and used to measure the branching ratio neutral-K2 to 2 neutral-pionsneutral-K2 to all modes. An upper limit of 0.0031 was obtained by normalizing to the neutral-K2 to 3 neutral-pion decay mode. Author
