Lifetimes in Ca isotopes: Large matter radii and halo-like neutron p-shells hypothesis in 50-52Ca: do we see evidence from spectroscopy?
Physics motivation
The large charge radii measured in 50-52Ca [Garcia] have proven a surprise from the experimental point of view, and a challenge for theoretical description. Not only laser spectroscopy has determined a large charge radius for...
The aim of this work is an investigation of the structural evolution
in neutron rich nuclei ``south and south-east'' of doubly-magic $^{48}$Ca,
especially with respect to rapidly changing nuclear properties. Here, we want
to investigate $^{46}$Ar, $^{48}$Ar and neighboring odd-A $^{47}$Ar and
$^{49}$K that are accessible in the same experiment. We will deduce unique
structural...
The nucleus 68Se presents two rotational band structures that have been identified, on the basis of the moments of inertia, as oblate and prolate. The ground state band, presenting the characteristics of an oblate rotational band, is crossed at spin 8+ by a prolate-deformed band that becomes yrast. The second excited state in this nucleus is a 2+ state, allowing to study experimentally the two...
The investigation of mirror nuclei along the N = Z line is of considerable interest since it directly addresses the validity of the charge symmetry of nuclear forces and the role of Coulomb effects in determining nuclear structure. Isospin symmetry breaking effects are important to probe theoretical corrections to the superallowed Fermi decay matrix elements I = 0+, T = 1 → I = 0+, T = 1...
Superallowed 0+→ 0+ β decay in light nuclei gives the most accurate Vud, the up-down mixing element of the Cabibbo-Kobayashi-Maskawa (CKM) matrix. In the Standard Model (SM), the matrix is supposed to have unitarity. The unitarity of the CKM matrix ensures that the three generations of quarks form a complete set of quark elements. In other words, the non-unitarity of the matrix implies the...
