Description
The Coulomb-excitation process with the combination of highly-efficient $\gamma$ and particle detector systems present a great tool to study quadrupole collectivity in nuclei and probing
nuclear-structure properties. This process employs the well-known Coulomb interaction and selectively excites collective nuclear states which decay back to the ground state through
$\gamma$-ray transitions. Coulomb-excitation measurements have been carried out by the UWC Coulex group, where various reorientation-effect Coulomb-excitation measurements (RECE) have recently been carried out f
or a systematic study throughout nuclei in the $sd$ shell. This work reports on our new measurements on $Q_{_S}(2^+_1)$ values at iThemba LABS and TRIUMF on $(^{12}C, ^{20}Ne, ^{32}S, ^{36}Ar \quad and \quad ^{40}Ar)$, which will be presented during this conference. In particular, a solution is proposed for the
striking zig-zag pattern of $Q_{_S}(2^+_1)$ values observed at the end of the $sd$ shell.
