“…Since 1956, fourteen measurements [4][5][6][7][8][9][10][11][12][13][14][15][16][17] have been made on the asymmetry coefficient A for 0 + of the 58 Co 58 Fe decay with a view to obtaining y. However, such measurements by either polarized nuclei or jS-y circular polarization correlations in unpolarized nuclei are difficult, and different workers tend to obtain rather different values.…”

Since 1956, fourteen experimentally-deduced values of the Fermi to Gamow-Teller mixing ratio y = CvMF/CAMGT were published, varying from 0.05 to -0.36 with most values consistent with y = 0, particularly those from recent measurements. Our calculation, using the Nilsson model, yields y= 2.07 x 10-4, which can be taken as zero. Our result is therefore consistent with time-reversal invariance. Furthermore, the vanishing value of y arises both from the ΔT selection rule and the ΔK selection rule
