Non-analog $\beta$- decay of $^{74}$Rb

The magnitude of the Coulomb mixing parameter $\delta^1\!\scriptstyle_\textrm{IM}$ has been experimentally deduced, for the first time, for the $\beta$-decay of $^{74}$Rb. The estimated magnitude is derived from the feeding of the non-analog first excited $0^+$ state in $^{74}$Kr. The inferred upper...

Descripción
Sumario:The magnitude of the Coulomb mixing parameter $\delta^1\!\scriptstyle_\textrm{IM}$ has been experimentally deduced, for the first time, for the $\beta$-decay of $^{74}$Rb. The estimated magnitude is derived from the feeding of the non-analog first excited $0^+$ state in $^{74}$Kr. The inferred upper limit of 0.07% is small compared to theoretical predictions. The half-life was measured to be 64.90(9) ms.
