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.”

My friend, Dilip Kondepudi, I met at UT Austin about 1974. He worked with Ilya Prigogine (Jan 1917 – 28 May 2003) who got his Nobel prize for thermodynamic systems far from equilibrium. But Dilip has studied “chirality” for decades since then. I asked Dilip to work on gravity with Prigogine and they did write a paper which might be relevant.

Many things involved with electron and positron reactions in isotopes also link to magnetic dipoles forces which are much stronger for electrons, are vector, and the technologies accessible now. I use magnetic dipole energies for the strong and weak force, since about 1974 when I was at UT Austin and they were actively aiming at fusion. But that is also because all the “good” fusion reactions were using strong magnetic fields and the “good” isotopes allow magnetic dipole binding. It means changing the model, but I think it is “magnetic fields all the way down”.

It should be possible to flip “parity” at will with pulsed KiloTelsa fields.
