Predecessor He-6 experiment

December 1949 Unpublished Richard L. Garwin An Experimental Investigation of the Beta-Gamma Angular Correlation in Beta Decay

Garwin's dissertation was in beta-gamma angular correlation. He later consulted with Wu about the errors in the Rustad-Ruby experiment.

 
February 15, 1953 Physical Review Brice M. Rustad and Stanley L. Ruby Correlation Between Electron and Recoil Nucleus in He6 Decay

First publication of Rustad-Ruby results. Together with Allen-Jentschke, seen as definitive determination of Tensor coupling in GT interactions

 
March 1, 1953 Physical Review D. C. Peaslee The Fermi Term in Beta-Neutrino Correlation

Success of Rustad-Ruby for GT interactions leads to search for similar experiment for F interactions. Peaslee was in the Wu orbit at Columbia and clearly had early knowledge of the Rustad-Ruby results. His letter was submitted before RR was published. Then the Peaslee letter was published in the very next issue.

Early paper by Morita cites Rustad-Ruby results one month after publication.

January 1, 1955 Physical Review D. R. Maxson, J. S. Allen, and W. K. Jentschke Electron-Neutrino Angular Correlation in the Beta Decay of Neon-19

October 1, 1956 Physical Review O. C. Kistner, A. Schwarzschild, and B. M. Rustad Decay of A35

Finds that A35 is a suitable source for identifying the Fermi invariant in the beta- decay interaction by an angular correlation experiment. Later, such an experiment by Hammersfeld was a key piece of evidence in the RR reversal.
