核子数目的守恒性是指核子不会自发衰变，也不会在核碰撞中单独被破坏或产生。这一守恒定律的有效性在1924年的实验中得到了验证，其结论是束缚核子的平均寿命为>；10/sup 22/年。据报道，通过使用延迟符合技术和放置在地下200英尺以下的巨型液体闪烁探测器阵列，这一数字得到了改进。(交流)
The conservation of the number of nucleons in the sense that they do not decay spontaneously nor are destroyed or created singly in nuclear collisions is generally assumed. The validity of this conservation law was tested experimentally in 1924 with the conclusion that a bound nucleon has a mean lifetime > 10/sup 22/ years. An improvement is reported on this number which is made possible by the use of a delayed-coincidence technique in conjunction with a giant liquid scintillation detector array placed 200 ft below ground.
