Relativistic Coupled Cluster Calculations,cal research is concerned. However, important physical and chemical processes involve heavy atoms, where relativistic effects cannot be ignored. Because relativistic and correlation effects play an essential role in the electronic structure of heavy-atom systems, relativistic many-body theories have

Correlation in Collisions,s elastic scattering scales simply with A, the number of nucleons, reflecting the constant density of nuclear matter. A microscopic calculation of this potential can be ordered so as to start with a zeroth order theory in which correlation is ignored, the independent particle model(IPM). A correctio

A speculative phase diagram (reproduced from Nagamiya and Gyulassyl) is shown in Figure. 1. Exotic states of nuclear matter are of interest in studying the physics

Realistic Microscopic Calculations of Nuclear Structure,n principle, this simply involves solving the many-body Schr?dinger equation: . for the eigenenergies .. and the eigenstates . of the many-particle system, where a is some label characterizing the states. But it is impossible to solve this problem in the full Hilbert space S when the number of parti

Microscopic Theories of Atomic and Nuclear Optical Potentials,ticle only feels a one-body potential, called the optical potential. The agreement between the calculated and experimental cross sections is so good that some authors adopt the viewpoint that the optical potential could be determined with unlimited accuracy if the exact elastic cross sections were k

The interaction plays a very important role when calculating spectra or formulating the existence criteria of weakly-damped excitations. The situation is quite different in the case of systems with a broken symmetry, as, for instance, spin

Impurity Distribution in Helium Droplets,up the possibility that their ground state structures can be probed by monitoring the changes in the impurities’ excitation spectrum. An essential first step toward this goal is to understand the distribution of impurities inside the droplet.
