dc.description.abstractCoulomb excitation reorientation e ects measurement was performed at the AFRODITE vault of iThemba LABS to determine the Qs(2+1 ) of 40Ar. A beam of 40Ar at a laboratory energy of 134.94 MeV was Coulomb excited on a 194Pt target at a safe distance between nuclear surfaces of 6.5 fm. The backward scattered 40Ar particles were detected by an S3-CD double sided silicon detector at a distance of 30 mm with an angular range of 130 to 159 . Eight HPGe clover detector array ( ve at 90 and three at 135 to the beam axis) was employed to detect the de-excited -ray energy emitted by the 40Ar particles. The 40Ar particles and their corresponding -rays were collected in coincidence and stored. MTsort MIDAS was used in conjunction with an o ine sorting code to sort the coincidence data. Coulomb excitation analytical code, GOSIA, was used to extract the diagonal matrix element, h2+1 kE2k2+1 i = 0:00(4) eb. From the relation, h2+1 kE2k2+1 i = Qs 0:75793 , the Qs(2+1 ) was determined as +0:00(3) eb. This result indicates a spherical shape for 40Ar at the 2+1 state.en_US
