    "abstract": "The relativistic coupled-cluster theory has been employed to calculate the\nmagnetic dipole and electric quadrupole hyperfine structure constants for the\nstable isotopes $^{45}$Sc and $^{89}$Y. The role of electron correlation is\nfound to be very important. The trend exhibited by these effects is rather\ndifferent from previously studied single valence atomic systems.",
