    "abstract": "We studied in a microscopic multiphonon approach the proton-neutron symmetry\nand phonon structure of some low-lying states recently discovered in 92Zr. We\nconfirm the breaking of F-spin symmetry, but argue that the breaking mechanism\nis more complex than the one suggested in the original shell model analysis of\nthe data. We found other new intriguing features of the spectrum, like a\npronounced multiphonon fragmentation of the states and a tentative evidence of\na three-phonon mixed symmetry state.",
