Nuclear Structure of $^{101}$Pd
POSTER
Abstract
$^{101}$Pd lies in a region of nuclei where A$\approx $110 and structural changes from vibrational to rotational are significant. In order to examine the nuclear structure of $^{101}$Pd, an experiment was performed at the Wright Nuclear Structure Laboratory at Yale University using the ESTU-1 Tandem Van de Graaff Accelerator. A beam of 70 MeV $^{12}$C collided with $^{92}$Zr target nuclei to produce $^{101}$Pd via the $^{12}$C + $^{92}$Zr $\to \quad ^{101}$Pd + 3$n$ reaction. Emitted $\gamma $-rays were detected by the SPEEDY array consisting of eight Compton-suppressed HPGe clover detectors. Then, $\gamma -\gamma $ coincidence measurements were made using RadWare to analyze the data. We were able to confirm many energy levels and observe several new ones. Also, new inter-band connections have been discovered. The structure of $^{101}$Pd was then interpreted using the strictly empirical E-GOS (E-Gamma Over Spin) method. The E-GOS plot, created by graphing energies of $\gamma $-rays over spin versus spin, revealed a clear transition from vibrational structure to rotational structure.
