摘要：

The rate of the CP-nonconserving decay KL0→2π0 has been measured relative to that of KL0→3π0 using a monoenergetic K beam and a nearly 4π solid-angle detector system employing lead-plate spark chambers and shower counters. The measured branching ratio 1.31% ± 0.18% (statistical) ±25% (systematic) leads to a value for the CP-nonconservation parameter |η00|2 of (14.1 ±3.4) × 10-6. © 1969 The American Physical Society.
