Suppressed electric quadrupole collectivity in ³²Si

NUCLEAR REACTIONS ¹⁹⁷Pt(³²S, ³²S), E=3.57 MeV/nucleon; measured charged particles after Coulomb excitation, Eγ, Iγ, (particles)γ-coin. ³²S; deduced B(E2), spectroscopic quadrupole moments. Coulex was evaluated using the semiclassical coupled channels Coulomb excitation code GOSIA. Demonstrated weakly deformed, centrally oblate nature of the ³²S. Comparison to theoretical calculations with shell model (USDB) and ab initio (VS-IMSRG) approaches. JANUS setup comprised of Segmented Germanium Array (SeGA) in a barrel configuration around S3-type annular silicon particle detectors up and down stream from the target at reaccelerated beam facility (ReA6) at NSCL.
