We aim at disentangling the second order-effects in Coulomb Excitation (Reorientation Effect and Nuclear Polarizability). A safe coulomb excitation experiment was performed to study the nuclear polarizability and reorientation effects through measuring the spectroscopic quadrupole moment Qs for the first 21+ in 40 Ar. A beam of 40Ar6+ at 134 MeV with typical currents of ≈ 0.5 to 1 nA was provided by the Cyclotron accelerator facility at iThemba Labs, which was Coulomb excited on a ≈ 1 mg ⁄ cm2 194Pt target. A double sided CD-type S3 silicon detector was used to detect particles at forward angels in coincidence with γ-rays. The dexcited γ-rays from the residual nuclei were detected using the AFRODITE array (5 clover detectors at 90° and 3 at 135°). A semi-classical couple channel Coulomb Excitation code, GOSIA, will be utilized to extract the matrix element for the Qs (2+) from the experimental data.
