Toroidal Modes in Nuclei by Inelastic Electron Scattering

Abstract

Electron scattering is a tool that can provide relatively clean view of the nuclear structure in both ground and excited states, as it depends on the well-known electromagnetic interaction. But since the common expressions for its cross section were derived with certain assumptions, in this paper we describe several nontrivial steps necessary for a proper theoretical calculation within the current density-functional framework, namely with Skyrme QRPA for axial nuclei, with aim to enable comparison of the theoretically predicted low-lying 1 − toroidal modes with future (e, e ) experiments.

Skyrme RPA for nuclear resonances: trouble with magnetic modes

“…This has consequences for many time-odd observables. For example, the current operator ˆ j q fails to satisfy the continuity equations if m * = m. The non-trivial kinetic terms in the mean-field Hamiltonian call for a dynamical correction which reads [19] ˆ…”
