  "abstract": "The lifetime of the J π = 2 + state in the self-conjugate Ru 88 nucleus has been determined in an experiment performed using rare-isotope beams provided by the new Facility for Rare Isotope Beams. This is the heaviest N = Z nucleus for which such a measurement has been achieved. Ru 88 was populated by both one-neutron knockout and charge-exchange reactions, and the lifetime of 14.3 − 3.4 + 2.5 ps was determined using the triple-foil plunger technique. The extracted electromagnetic transition strength shows that the quadrupole collectivity has dropped significantly compared with the highly deformed N = Z region around A ∼ 80 . These results are compared with state-of-the-art large-scale shell-model and discrete nonorthogonal shell-model calculations. The theoretical calculations indicate a moderate triaxial deformation and suggest that low-lying states in this nucleus are no longer dominated by strong many-particle many-hole excitations, unlike the lighter, highly deformed N = Z nuclei nearby.",
