dc.description.abstractThe search for the theoretically predicted tetrahedral states has been the source of much interest in recent years with studies of the nuclear structure at low spin states. In this work we have looked for low spin non-yrast states of the even-even nucleus ¹⁶⁰Yb populated through the electron capture or β⁺-decay of ¹⁶⁰Lu. The radioactive ¹⁶⁰Lu source was created through the heavy-io fusion evaporation reaction ¹⁴⁴Sm(¹⁹F,3n) at a beam energy of 85 MeV. Both ϒ-ϒ coincidences and single ϒ rays were detected using the AFRODITE Ge detector array at iThemba LABS. The computer program EONS was developed to measure the half-life of single ϒ rays for identification. The level scheme constructed from the ϒ-ϒ coincidence and single ϒ ray measurements confirms the existing level structure of ¹⁶⁰Yb. Population of low spin states was success and two new levels have been found, the 1755 ke V level decays by a 1512 keV ϒ ray and 1825 kev level decays through 1582 keV.en_ZA
