Raymond W. Hayward
Nuclear physicist and parity-test collaborator
Who they are
Raymond W. Hayward was a National Bureau of Standards physicist and one of five authors of the 1957 cobalt-60 parity experiment. He subsequently worked in radioactivity and led a nuclear-spectrometry section. His contribution belongs to a shared experimental result that showed a weak-interaction process need not behave like its mirror image.
His profile makes the NBS team’s contribution to the parity result visible alongside Wu’s leadership and the Lee–Yang proposal.

Experimental Test of Parity Conservation in Beta Decay
Wu, Ambler, Hayward, Hoppes and Hudson report an asymmetry in electrons emitted by polarized cobalt-60 nuclei. The experiment tests parity conservation in a specified weak decay rather than establishing a claim about all physical processes.
