New spin-orbit interactions and isotope shifts

An MCHF atomic-structure package for large-scale calculations

An MCHF atomic-structure package is presented based on dynamic memory allocation, sparse matrix methods, and a recently developed angular library. It is meant for large-scale calculations in a basis of orthogonal orbitals for groups of LS terms of arbitrary parity. For Breit-Pauli calculations, all operators – spin-orbit, spin-other orbit, spin-spin, and orbit-orbit – may be included. For trans...

Isospin dependence of the spin-orbit force and effective nuclear potentials.

The isospin dependence of the spin-orbit potential is investigated for an effective Skyrme-like energy functional suitable for density dependent Hartree-Fock calculations. The magnitude of the isopin dependence is obtained from a fit to experimental data on finite spherical nuclei. It is found to be close to that of relativistic Hartree models. Consequently, the anomalous kink in the isotope sh...

Spin–orbit interactions, new spectral data, and deperturbation

We report calculations of the spin–orbit energy as a function of internuclear distance R within the b )u state of K2 , and between the b )0u and A (u 1 states, together with new spectroscopic data on the b state and previously unpublished data on the A state. Both the new data and previous data are fitted to Hamiltonian parameters using the discrete variable representation ~DVR! method. The DVR...

Sagnac rotational phase shifts in a mesoscopic electron interferometer with spin-orbit interactions

0 Fixed energy inversion of 5 eV e - Xe atom scattering

Fixed energy inverse scattering theory has been used to define central and spin-orbit Schrödinger potentials for the scattering of 5 eV polarized electrons from Xe atoms. The results are typical for a range of such data; including energies above threshold when the potentials become complex. The phase shifts obtained from an analysis of the measured differential cross section and analyzing power...
