摘要

这封信报告了旨在寻找介子K的2m衰变的实验研究的结果。先前的几个实验已经为K2衰变为两个带电介子的比例设定了1/300的上限。目前的实验，使用火花室技术，提出扩大这一限制。

Evidence for the $2\pi$ Decay of the $K_2^0$ Meson

This Letter reports the results of experimental studies designed to search for the 2m decay of the K, meson. Several previous experiments have served"~ to set an upper limit of 1/300 for the fraction of K2 's which decay into two charged pions. The present experiment, using spark chamber techniques, proposed to extend this limit.
