Self-consistent description of multipole strength: Systematic calculations

We use the quasiparticle random-phase approximation with a few Skyrme density functionals to calculate strength functions in the J π = 0+, 1−, and 2+ channels for even Ca, Ni, and Sn isotopes from the proton drip line to the neutron drip line. We show where and how low-lying strength begins to appear as N increases. We also exhibit partial energy-weighted sums of the transition strength as func...

Isoscalar Resonances with J

Local geometry of isoscalar surfaces.

An inert dynamically passive scalar in a constant density fluid forced by a statistically homogeneous field of turbulence has been investigated using the results of a 256(3) grid direct numerical simulation. Mixing characteristics are characterized in terms of either principal curvatures or mean and Gauss curvatures. The most probable small-scale scalar geometries are flat and tilelike isosurfa...

Spectral Content of Isoscalar Nucleon Form Factors

The nucleon strange vector and isoscalar electromagnetic form factors are studied using a spectral decomposition. The KK̄ contribution to the electric and magnetic radii as well as the magnetic moment is evaluated to all orders in the strong interaction using an analytic continuation of experimental KN scattering amplitudes and bounds from unitarity. The relationship between non-resonant and res...
