Alpha Cluster states in O

ORAL

Abstract

search for $\alpha $-cluster states is an open and interesting question in nuclear structure and has implications for the understanding of helium burning in stars. We carried out an experiment to explore $\alpha $-cluster states above the 4$\alpha $-decay threshold in via the ($\alpha $,n) reaction at the University of Notre Dame's Nuclear Science Laboratory. The experimental setup included four double-sided strip detectors with 256 channels to measure energies and angular distributions of charged particles and 12 deuterated liquid scintillators were used to detect neutrons in the angular range 22\textordmasculine \textordmasculine . By reconstructing reaction kinematics $\alpha $-cluster levels in can be obtained. The experimental setup and preliminary results will be presented. work was supported by the NSF under contract number PHY -- 1419765.
