High spin intruder states of $^{47}$Sc and $^{48}$Sc using fusion evaporation reactions

POSTER

Abstract

Identifying collective states with clear n-particle-n-hole structure near closed shells can reveal deformation driving orbital characteristics. Such states, often high-spin in nature, can be populated using the fusion-evaporation reaction mechanism, extracted using gamma-ray spectroscopy techniques and compared to state-of-the-art theoretical shell model calculations. Recently, an experiment to look for intruder states in $^{47,48}$Sc was done using the $^{36}$S$(^{14}$C$,p)$ and $^{36}$S$(^{14}$C,$pn)$ reactions at 34-MeV performed at Florida State University's John D. Fox superconducting Laboratory. The experimental setup included an array of HPGe detectors surrounding the enriched $^{36}$S as well as a Si particle detector telescope located at zero-degrees with respect to the beam axis. The telescope has allowed specific reaction residue to be correlated with observed $\gamma$-rays. We present preliminary results from the experiment.
