Description
We have investigated the seniority feature of $^{94}$Pd with its level lifetime measured by the fast-timing technique. The experiment was carried out at the Radioactive Isotope Beam Factory (RIBF) at RIKEN. $^{94}$Pd was produced by in-flight fragmentation of a $^{124}$Xe primary beam impinging on the $^{9}$Be target. The secondary cocktail beams were identified using the BigRIPS separator and implanted into the segmented plastic active stopper at one of the focal points, F11. The gamma rays emitted from the isomeric decay of $^{94}$Pd were detected by the International Detector Assembly for fast-Timing measurements of Exotic Nuclei (IDATEN) array, consisting of 48 LaBr$_{3}$(Ce) detector modules. The high-statistics data obtained by the Twinpeaks+TAMEX4 DAQ system enables us to determine more precisely the half-life of the first 8+ state in $^{94}$Pd. These results are expected to provide critical insights into the seniority effects in the region adjacent to the doubly magic nucleus $^{100}$Sn.
