Absolute Measurements of Anomalousεβ+-Decay Branching Ratios

Absolute values of $\frac{\epsilon }{{\beta }^{+}}$-decay branching ratios for decay of ${}_{}{}^{145}{}_{}{}^{}\mathrm{Gd}$ to twelve levels in ${}_{}{}^{145}{}_{}{}^{}\mathrm{Eu}$ have been measured. These measurements are all shown to deviate substantially from the calculated $\frac{\epsilon }{{\beta }^{+}}$ ratios of Gove and Martin. Skew ratios (exp/theor) are found to range from 1.5 to 40. These "anomalies" are ascribed to second-order corrections to allowed decay which have not been included in the calculations.
