Evidence for Breakdown of Vibrational Motion in $^{110}$Cd
ORAL
Abstract
$^{110}$Cd has long been considered an excellent example of a vibrational nucleus. However, recent work with other even-even Cadmium isotopes show a breakdown of vibrational motion at the 2 and 3-phonon level, suggesting the need for more precise measurements on $^{110}$Cd. The structure of $^{110}$Cd is studied with the ($n,n^{\prime}\gamma$) reaction performed at the University of Kentucky, as well as with the high statistics $\beta$-decay of $^{110}$In performed at the TRIUMF-ISAC facility using the 8$\pi$ spectrometer. Excitation funcions and angular distributions from the ($n,n^{\prime}\gamma$) reaction provide us with spectroscopic information on the level scheme, including level lifetimes and spins. This data is complemented by the $\gamma\gamma$ coincidences measured in the $^{110}$In $\beta$-decay that allows the observation of, or stringent limit on, weak, low-energy branches between levels at high excitation energy. Details of the analysis to date, including candidates for the full octupole-quadrupole coupled quintuplet, will be presented.
