Coupled-cluster computations of atomic nuclei.

چکیده
In the past decade, coupled-cluster theory has seen a renaissance in nuclear physics, with computations of neutron-rich and medium-mass nuclei. The method is efficient for nuclei with product-state references, and it describes many aspects of weakly bound and unbound nuclei. This report reviews the technical and conceptual developments of this method in nuclear physics, and the results of coupled-cluster calculations for nucleonic matter, and for exotic isotopes of helium, oxygen, calcium, and some of their neighbors.

A Variety of Giant Resonances in Metal Clusters
Metal cluster (MC) is a bound system consisting of atoms of some metal. The amount of atoms can vary from a few to many thousands. Some MC, mainly of alkali (Li, K, Na, ...) and noble (Ag, Au, ...) metals, demonstrate a striking similarity to atomic nuclei (see reviews). In these clusters the valence electrons are weakly coupled to the ions and, like nucleons in nuclei, are not strongly localiz...
متن کاملQTAIM study of Bonding and Structure of Pure Atomic Clusters,Part III : Nn Clusters (n= 4,6)
DFT and QTAIM computations have been performed on numbers of pure nitrogen cluster speciesi.e. Nn (n = 4, 6) for investigating the structure and bonding. This study is critical since thesemolecules have been nominated as the good synthetic targets of High Energy Materials (HEM).0nthe other hand the decomposition mechanism is closely depends on the bonding pattern. Thislatter concept was searche...
متن کاملSpectroscopic LSJ notation for atomic levels obtained from relativistic calculations
Today, relativistic calculations are known to provide a very successful means in the study of open–shell atoms and ions. But although accurate atomic data are obtained from these computations, they are traditionally carried out in jj−coupling and, hence, do often not allow for a simple LSJ classification of the atomic levels as needed by experiment. In fact, this lack of providing a proper spec...
متن کاملHelium halo nuclei from low-momentum interactions
We present ground-state energies of helium halo nuclei based on chiral low-momentum interactions, using the hyperspherical-harmonics method for He and coupled-cluster theory for He, with correct asymptotics for the extended halo structure.
متن کاملTheoretical overview of atomic parity violation Recent developments and challenges
Recent advances in interpreting the most accurate to-date measurement of atomic parity violation in Cs are reviewed. The inferred nuclear weak charge, QW ( Cs) = −72.65(28)expt(36)theor, agrees with the prediction of the standard model at 1σ level. Further improved interpretation is limited by an accuracy of solving basic correlation problem of atomic structure. We report on our progress in sol...
