Wu’s parity violation is likely magnetic for strong (MeV) and weak (KeV) isotope reactions
Zhigang Suo @zhigangsuo The Nobel Laureate T.D. Lee died recently. @yangyang_cheng wrote about Lee’s role in lifting science in China, and in bridging China and America.
These magical years of 1980s! https://npr.org/2024/09/05/nx-s1-5092630/td-lee-legacy-perspective-china-physics-yangyang-cheng

Thanks for sharing!
There have been many excellent and outstanding researchers from China working in China and around the world. Tsung-Dao Lee (24 Nov 1926 – 4 Aug 2024) at https://en.wikipedia.org/wiki/Tsung-Dao_Lee
In the United States, and for me, it was Chien-Shiung Wu who had more impact. (31 May 1912 – 16 Feb 1997) https://en.wikipedia.org/wiki/Chien-Shiung_Wu
Without her, a theory would not have been tested. But it never seemed to develop into new technologies or practical insights. I will look again, but it has always felt wrong to me. Even the NobePrize.Org prize motivation hints: “for their penetrating investigation of the so-called parity laws which has led to important discoveries regarding the elementary particles”.
They did not use it for anything. Sort of “We think the rule is broken, Wu tested it and she said that proved it, but we do not know how it works at a physical level, and cannot use it for anything practical”
Looking at https://www.nndc.bnl.gov/nudat3/ for Cobalt 60 (Z=27, N=33, N-Z=6, N+Z=60) I see many ways to go deeper. That 5+ just looks wrong to me and 0.25% of 2+.)
I know my own immediate reaction reading about Wu’s experiment the first time: “Of course it will do that, electrons are diamagnetic, so use stronger pulsed magnetic gradients.”
It should be possible to flip “parity” at will with pulsed KiloTelsa fields.
