Beta Decay

Comment(s): 

Wu's more distant review of the He6 events

Excerpt(s): 

Evidence for V—A Interaction. Suddenly many doors swung open to lead to the determination of the β interactions.


The early experimental results indicated that a is close to +1/3, favoring a tensor interaction. However, more recent experiments (He-58; Al-59), whose arrangements are shown in

Prove. Inclusively that coefficient a in Gamow-Teller is negative, being in fact close to the expected value of -1/3 for the axial-vector form. This result has been confirmed by the Oak Ridge group (Jo-63) with a more refined setup

Angular Correlations

R-R cited in detail as definitive ST

Excerpt(s): 

In practice, the correlation is made between the electron and the nuclear recoil. The transformation between the correlations of the two types has been examined in detail by KOFOED-HANSEN. Electron recoil nucleus correlations in the allowed β-decay He6—>Li6, involving only a Gamow-Teller interaction, have been measure by RUSTAD and RUBY. Experimentally conditions here are also favorable to precise measurements, since the large energy of the β-transition and the light nucleus result in large recoil energies.

The Measurement of Electron-Neutrino Angular Correlations [and Discussion]

B. W. Ridley and discussants
Proceedings of the Royal Society of London. Series A, Mathematical and Physical Sciences
Aug 26 1958
Excerpt(s): 

A. Salam, Imperial College: Could Dr Ridley say, if he were asked to choose between these two diagrams, which would he prefer?
B. W. Ridley: I think I am all right in saying that the 35A point is fairly certain, because it would have to move a very long way to change the picture significantly, and one feels that the 19Ne results are significant, merely from the weight of what are now four inde- pendent experiments. A. Salam: So you would be inclined to discount the 6He experiments if you had to choose?
