E0 components of J$^\pi\rightarrow$J$^\pi$ Transitions in $^{154}$Gd}

ORAL

Abstract

E0 components of transitions between two states of the same spin and parity are challenging to measure, with sparse information available in nuclear databases. A recent study of $^{154}$Gd (D. A. Meyer et al, PRC 044309(2006)) showed the nucleus to have 16 0$^+$ states. $^{154}$Gd is well-studied by a number of reactions, hence it is an ideal candidate to search for E0 transitions. We will report on our results for transitions in $^{154}$Gd following the $^{152}$Sm($\alpha$,2n) reaction using the Internal Conversion Electron Ball (ICEBall) array in coincidence with $\gamma$-rays at the University of Notre Dame Nuclear Science Laboratory (NSL). ICEBall was re-implemented at the NSL 4 years ago and the $\gamma$-rays were detected by Clovershare, segmented HPGe detectors purchased by the Yale Nuclear Structure Laboratory that are shared by a consortium of universities and laboratories for experimental campaigns.
