122. Perspectives for laser spectroscopy at the next generation of European RIB facilities

Nuclear structure far from stability

Oral

The last 10 years have witnessed significant advances in field of laser spectroscopy. Leaps in detection sensitivities through continued development at existing on-line facilities have pushed measurements towards fringes of the nuclear chart. The application of laser probing for rare isotope production and purification has established itself as a mature field in its own right. Synergy...

17. Ground States and Isomers of Cadmium by High-Resolution Laser Spectroscopy

Dr D. T. Yordanov (Max-Planck-Institut für Kernphysik, Saupfercheckweg 1, D-69117 Heidelberg, Germany)

5/22/12, 9:30 AM

Nuclear structure far from stability

Oral

We report on the first hyperfine-structure study of cadmium by high-resolution laser spectroscopy. The goal is to determine nuclear spins, electromagnetic moments and root mean square charge radii of ground and isomeric states along the chain, ultimately reaching the neutron 50 and 82 shell closures. In the first part of the program we studied the intense beams of 106-124,26Cd by fluorescence...

29. The observation of a strong E0 component in the 2+2-->2+1 transition in 184Hg from the beta-decay of laser-ionized thallium isotopes: a strong signature for shape coexistence.

Nuclear structure far from stability

Oral

The mass region of neutron-deficient mercury and lead isotopes near the midshell (N=104) is well known for the phenomenon of shape coexistence. In neutron-deficient, even-even 180-188Hg isotopes an oblate (beta2~-0.15) ground state band is found to coexist with an excited prolate (beta2~0.25) band at low spin and low-excitation energies. This band is built on top of a deformed excited 0+...

116. A diynamical model for halo nuclei and two-nucleon transfer reaction

Enrico Vigezzi (INFN Milano, Italy)

5/22/12, 10:10 AM

Nuclear structure far from stability

Oral

The peculiar properties of the halo nuclei 11Li and 12Be can be successfully interpreted in the framework of a dynamical model based on the interweaving of single-particle levels with the collective vibrations of the system, leading to a substantial admixture of phonons in the ground state. This interweaving induces an attractive interaction between the two-halo neutrons that in the model is...

62. Ab-initio Green's function calculations of medium-mass open-shell nuclei

Dr Vittorio Somà (EMMI/TU-Darmstadt)

5/22/12, 10:40 AM

Nuclear structure far from stability

Oral

Ab-initio approaches - starting from the sole knowledge of a realistic nuclear force - aim at eventually achieving parameter-free predictions of nuclear properties. Although considerable progress has been made in recent years, e.g. using couple-cluster or self-consistent Dyson-Green's function methods, ab-initio nuclear structure calculations of medium-mass and heavy nuclei are still...
