The Zirconium isotopes across the N=56,58 neutron sub-shell closures have been of special interest since years, sparked by the near doubly-magic features of
96 Zr and the subsequent rapid onset of collectivity with a deformed ground-state structure already in100 Zr. Recent state-of-the-art shell model approaches did not only correctly describe this shape-phase transition in the Zr isotopic chain, but alsothe coexistence of non-collective structures and pronounced collectivity especially in96,98 Zr. Theisotope98 Zr is located on the transition from spherical to deformed ground state structures. We summarize recent experimental work to obtain the B(E2) excitation strengths of the first 2+ state of98 Zr, including a new experiment employing the recoil-distance Doppler-shift method following a two-neutron transfer reaction.
