$\beta$-delayed spectroscopy of neutron-hole single particle states in $^{133}$Sn*

The nuclear beta-decay offers a well understood and selective probe to study the structure of the daughter. Close to magic nuclei, this selectivity can be exploited to study the properties of states involving specific single-particle orbitals. Neutron single-hole states in $^{133}$Sn were studied for the first time in the beta-delayed neutron emission of $^{133}$In at the ISOLDE facility, CERN. Neutron energies and intensities were observed using the IDS Neutron Detector, a time-of-flight detector array consisting of 26 plastic scintillator bars [1]. Preliminary results will be discussed. \\ \\ ~[1] W.A. Peters et al., Nucl. Instr. and Meth. A836, 122 (2016).
