We demonstrate the feasibility of realistic Shell Model Monte Carlo (SMMC) calculations spanning multiple major shells, paying particular attention to the center-of-mass motion. We then use this method to study a series of unstable neutron-rich nuclei with active nucleons in both the sd and pf major oscillator shells. In particular, we study nuclei around the two presumed shell closures at N = ...

The isospin dependence of the spin-orbit interaction in light neutron rich nuclei is investigated in the framework of relativistic mean field theory. The magnitude of the spin-orbit potential is considerably reduced in drip line nuclei, resulting in smaller energy split-tings between spin-orbit partners. The effect does not depend on the parametrization of the effective Lagrangian. The results ...

We present some highlights from the mid-infrared (5-16 μm) images of mergers of massive galaxies obtained with the Infrared Space Observatory (ISO). We have observed: 1) ultraluminous infrared nuclei, 2) luminous dust-enshrouded extranuclear starbursts, and 3) active galaxy nuclei (AGNs). In this contribution we discuss the observations of Arp 299, a prototype for very luminous infrared galaxie...

Coulomb energy differences between mirror nuclei with A ≤ 70 are calculated within the framework of the nuclear shell model using an effective Coulomb plus isovector and isotensor interaction. Absolute binding energies for proton-rich nuclei are predicted by adding the calculated Coulomb shifts to experimentally measured binding energies for the neutron-rich mirror. The location of the proton d...
