The multiconfiguration Dirac-Fock model is employed to evaluate the effects of relativity and electron correlation on the hyperfine interaction constants of the 3d{sup 2} {sup 3}F{sub 3}, {sup 3}F{sub 4}, {sup 1}G{sub 4}, and 3d4p {sup 3}F{sub 4} levels of ScII. The wave function expansions are obtained with the active space method, where configuration state functions of a specific parity and J value are generated by substitutions from the reference configurations to an active set of orbitals. The active set is then increased in a systematic way, allowing the convergence of the hyperfine interaction constants to be studied. The calculated electric quadrupole hyperfine constants, together with previously computed values for other levels of ScII, are used to evaluate the nuclear electric quadrupole moment of isotope 45 of scandium, for which the value Q={minus}0.231(4) b is found. {copyright} {ital 1997} {ital The American Physical Society}
