    Notizen: Abstract To clarify the physical nature of the orbital magnetic dipole excitations discussed widely in the past few years, a semiclassical model is presented and the nuclei156Gd and164Dy are investigated microscopically. The semi-classical model involves a consistent treatment of vibrational and rotational degrees of freedom; the microscopic results are obtained in quasiparticle-random-phase approximation (QRPA) with a realistic effective interaction. The results disagree with the picture of scissors modes or rotational vibrations.

    M1 resonances in unstable magic nuclei (1993)

    Notizen: Abstract Within a microscopic approach which takes into account RPA configurations, the single-particle continuum and more complex 1p 1 h⊗phonon configurations isoscalar and isovector M1 excitations for the unstable nuclei56,78Ni and100,132Sn are calculated. For comparison, the experimentally known Ml excitations in40Ca and208Pb have also been calculated. In the latter nuclei good agreement in the centroid energy, the total transition strength and the resonance width is obtained. With the same parameters we predict the magnetic excitations for the unstable nuclei. The strength is sufficiently concentrated to be measurable in radioactive beam experiments. New features are found for the very neutron rich nucleus78Ni and the neutron deficient nucleus100Sn.
