ENSAR - European Nuclear Science and Applications Research. KU Leuven
ENSAR is the Integrating Activity of Nuclear Scientists from almost all European countries performing research in three of the major subfields of Nuclear Physics: Nuclear Structure, Nuclear Astrophysics and Applications of Nuclear Science. It proposes an optimized ensemble of Networking (NAs), Transnational Access and Joint Research Activities (JRAs), which will ensure qualitative and quantitative improvement of the access provided by the ...
Laser ionization based gas cell developments and laser spectroscopy in the region around 100Sn and the heavy Ac isotopes. KU Leuven
Recently it has been proved at the Leuven Isotope Separator On Line (LISOL) facility that laser spectroscopy inside a gas cell coupled to a mass separator provides a new way to obtain moments and charge radii of far unstable nuclei of chemical elements that are difficult to produce at standard ISOL facilities. This project aims to improve the methode in its efficiency, resolution and range of elements. Dr. Ferrer is an expert in simulating, ...
Determination of recoil terms in beta decay. KU Leuven
Precise measurements of the so-called beta emission asymmetry in pure Gamow-Teller beta decay areasensitive probe to search for an as yet unobserved tensor component in the weak interaction. Recently, new development in our group have lead to the most precise measurements of this type ever performed. Further developements should lead to an even higher precision. At the current precision level of 1% additional, small correction terms that are ...
Lattice location study of dopant imputities in group-IV semiconductors. KU Leuven
The lattice location of dopant elements in a semiconductor crystal highly influences the electrical, optical or magnetic activity of the dopants, which in turn affects the semiconductor properties. In this research project, the lattice location of electrical dopants in group IV semiconductors will be studies in detail: boron (B), phosphorous (P), indium (In) and antimony (Sb) in silicon and germanium. Several experimental techniques such as ...
Two-neutron transfer reactions with radioactive beams. KU Leuven
The region around the nucleus 68Ni, with a shell closure for its protons at Z=28 and a harmonic oscillator shell gap for its neutrons at N=40, has drawn considerable interest over the past decades. 68Ni has properties that are typical for a doubly-magic nucleus, such as a high excitation energy and low B(E2:2+->0+) transition probability for the first excited 2+ level and a 0+ level as the first excited state. However, it has been suggested ...
Nuclei under extremes. KU Leuven
Since its inception, the study of atomic nuclei has largely been limited to nuclei near the valley of stability. Theories and paradigms have been developed based on data from those nuclei. Now, in the last decade, through technological and theoretical advances, it has become possible to produce and study nuclei far from stability in great detail. These nuclei possess truly exotic, unforeseen properties that challenge these paradigms, the ...
Search for a tensor component in the weak interaction Hamiltonian KU Leuven
The search for physics beyond the standard model can, besides in high-energy experiments such as the ones at the LHC accelerator, also be carried out at lower energies. Measurements of correlation coefficients in neutron and nuclear beta decay constitute a reliable and model-independentmethod for such efforts.

Measurement of the electric dipole moment of the neutron. KU Leuven
The neutron electric dipole moment is being measured with ultracold neutrons. A non-zero value would point to a new type of CP-violation, much larger than the one that is already included in teh Standard Model This would yield new information on the as yet unexplained baryon asymmetry in the universe. The measurements use the ramsey technique and are performed at the ILL-Grenoble (until the end of 2008) and at the Paul Scherrer Institute ...
