Anecdote involving Feynman and Wu at the 1958 APS meeting
Or does the author mean 1957?

Excerpt(s): 

In January 1958 I attended the meeting of the American Physical Society in New York where Wu presented the results of her experiment on parity violation in beta decay of cobalt-60. In a 20 minute talk she described the experiment and announced that the result was that beta-decay indeed violated parity conservation and the combination of amplitudes was S+T, the sum of the scalar and tensor currents.

Experimental Evidence for Non-Conservation of Parity and Charge Conjugation in Beta Decay

Comment(s): 

Wu obliquely refers to classic experiments but focuses on post-parity work

Excerpt(s): 

Introduction. Dr. Lee has just given us an excellent talk on the theoretical implication of parity non-conservation in β-decay. He also outlined the various experimental evidences which one would expect to observe under various combination of the coupling constants. The maximum number of coupling constants to be determined thus has leaped from a mere five for the old theory to thirty five or thirty eight in all at the present state. Fortunately, possible means and methods for the investigation of these coupling constants are also greatly increased and extended.

Theoretical Implications of Parity Violations in Beta Interactions

Excerpt(s): 

In this idealized simple situation we can predict from the three measurements the results on recoil measurement in mixed or Fermi transition, the helicity of electrons and positrons, the rate for double β decay, etc. While it is true that the present experimental results x on He6, Co60, Sc46 are not incompatible with this simple situation, due to the largeness of all experimental errors it certainly does not yet prove that this simple situation is the reality.

Covers Garwin's recollections of the parity violation experiments, including his role directing Wu to NBS and the circumstances of his and Lederman's K-meson experiment.
