吴健雄钴-60原子核β衰变证明宇称不守恒实验中的错误

吴健雄钴-60原子核β衰变证明宇称不守恒实验中的错误

Abstract

1957年1月,吴健雄用两套实验装置来观测钴60的衰变,她在极低温(0.01K)下用强磁场把一套装置中的钴60原子核自旋方向转向左旋,把另一套装置中的钴60原子核自旋方向转向右旋。她根据两套实验装置中的钴60原子核自旋方向相反,就认为这两套装置中的钴60互为镜像。这当中其实存在一个非常重大的错误,这个错误就是,人们对镜像对称和旋转对称的理解,以及钴60原子核自旋原理认知上的错误。两套实验装置中自旋方向相反的钴60原子核,其实并非镜像对称,而是180°的旋转对称。 什么是镜像对称?什么又是旋转对称?吴健雄在钴60的衰变的试验中,由于对这两种对称的误解,最后造就了一个错误的“宇称不守恒”的实验结论。本论文不讨论“宇称不守恒”理论本身正确与否,只是讨论通过观测两个自旋方向相反的钴60衰变,到底是否可以来验证“宇称不守恒”的问题。
