$\gamma$-rays following the $\beta$-decay of $^{62}$Ga and the strength of the superallowed transition

As part of an ongoing study of superallowed $\beta$-decay at TRIUMF, we have measured the intensity and energy of $\gamma$- rays following the $\beta$-decay of $^{62}$Ga. During a beam on period of 10 s., a total of approximately 3$\times$10$^{8}$ atoms of $^{62}$Ga, from the Resonant Laser Ionisation Source at the ISAC facility, was implanted into a collector tape at the centre of the SCEPTAR/8$\pi$ arrays. Before and after the beam on period, 2 s. of data were taken to assess backgrounds and the build up of long-lived activities. After each counting cycle the tape was moved in order to transport the implanted atoms to a shielded location. Substantial reduction in the Bremsstrahlung induced background were achieved by vetoing events in which the $\beta$-rays and $\gamma$-rays were observed in corresponding detectors. Singles $\beta$ and coincident $\beta$-$\gamma$ events were recorded. The intensities of $\beta$-rays feeding of low lying states in $^{62}$Zn and a $\gamma$-decay scheme of $^ {62}$Zn are proposed. The data are compared to shell model predictions of energies and transition strengths. Predictions of charge dependent effects are tested against the deduced superallowed transition probability.
