Fermi—Gamow-Teller interference in 56Co decay


A measurement of the circular polarization of the γ rays following the β decay of 56Co reveals an anisotropy coefficient of A=0.017(13). A Fermi to Gamow-Teller ratio, MFCV/MGTCA=-0.13(2), was derived demonstrating a sizable interference between the two amplitudes.
