Excited states of 90Zr and 92Zr were investigated using the fusion reactions 6Li + 89Y and 14N + 82Se , respectively. Based on the experimental data, 5 and 18 new 𝛾 rays have been added to the level schemes of 90Zr and 92Zr , respectively. The level structures of 90Zr and 92Zr have been interpreted with shell-model calculations using the GWBXG and SNET effective interactions. The neutron core-breaking and the importance of the 1⁢𝑔7/2 and 1⁢ℎ11/2 orbits for high-spin states of 92Zr were discussed. Finally, the excitation energy of the neutron core-breaking of nuclei in the 𝐴=90 region was compared.
