    "abstract": "Low-energy intrinsic $K^\\pi$=1$^+$, $0^-$, $1^-$, $2^-$, and $3^-$ states in\nthe even-even proton-rich Sr, Kr, and Zr nuclei are investigated using the\nquasiparticle random phase approximation. In the Z$\\simeq$N nuclei the\nlowest-lying 1$^+$ states are found to carry unusually large $B(M1)$ strength.\nIt is demonstrated that, unlike in the heavier nuclei, the octupole\ncollectivity in the light zirconium region is small and, thus, is not directly\ncorrelated with the systematics of the lowest negative parity states.",
