Low energy states in $^{124,126}$Cd Populated via the Beta Decay of $^{124,126}$Ag

The lowest lying levels in the neutron-rich even-even Cd isotopes have structures that resemble an anharmonic vibrator coupled to 2-proton intruder states. Deviations from this picture have been shown to occur in $^{112-120}$Cd isotopes [1,2]. To determine the systematics of these states across the neutron shell we have begun to measure the beta decays of the heavier even-mass Ag isotopes. $^{124,126}$Ag ions were produced via the proton-induced fission of U at the HRIBF at ORNL. 15 microA of 50 MeV p bombarded on a UCx target, and the fission products were then separated by a high-resolution magnetic isobar separator and deposited on a moving tape collector directly in the center of the LeRIBSS (Low-Energy RIB Spectroscopy station) array. Many new levels in $^{124,126}$Cd have been observed. These results and the systematics of the even-even Cd isotopes will be presented and discussed.\\[0pt] [1] K. L. Green,et al., Phys. Rev.
