Experimental Evidence for the Fermi Interaction in the Decay of and
R Sherr, JB Gerhart - Physical Review, 1953 - APS
The γ-ray spectra of O 14 and C 10 have been investigated with a NaI scintillation spectrometer.
A value of 2.30±0.03 Mev was found for the O 14 nuclear γ ray. C 10 has two γ rays with …

Decay and the Fermi Coupling Constant in Beta Decay
JB Gerhart - Physical Review, 1954 - APS
Because the constant ot is fixed by the demand that the total energy of the meson field be
equal to the selfenergy of the nucleon, Mc'= 938 Mev, and because, as a consequence of A (0) …
