Low-energy physics
- Magdalena Kowalska (Universite de Geneve (CH))
The search for physics beyond the standard electroweak model (SM), despite its remarkable success at the most elementary level, still continues on three frontiers - high-energy, precision and cosmic. The reason is the many yet unanswered questions such as the origin of parity violation [1].
Considering the precision frontier, experiments with radioactive nuclei offer large variety of nuclear...
Stars of 7-11 solar masses are prevalent in the Galaxy, their birth and death rate comparable to that of all heavier stars combined. Yet, the ultimate fate of such “intermediate-mass stars” remains uncertain. According to current models a significant fraction explode, but the mechanism is a matter of ongoing debate. The answer ─ gravitational collapse or thermonuclear explosion ─ depends...
Excited state of odd-mass isotopes can be in general used as a proble of the structure of even-even cores. The odd particle or hole acts as a spectator and ordering and energies of excited states reveal information on, e.g., axial and triaxial deformation. In particular, excitation energy of low-spin states is very sensitive to triaxial parameter of the core. However, such states are usually...
Simple systems in the proximity of the doubly-magic shell closures constitute the best cases for testing the predictive power of shell-model calculations. In this context, understanding of the nuclear structure in the closest vicinity of the doubly-magic $^{132}$Sn is essential before making extrapolations of the nuclear properties towards more neutron-rich nuclei. Recently, it was indicated...
The neutron-deficient mercury isotopes ($Z=80$) around $N=104$ represent one of the most prominent examples of shape coexistence [1]. This region has been extensively studied using various experimental techniques, such as laser spectroscopy [2,3], decay spectroscopy studies [4,5] and Coulomb excitations [6,7]. These studies point to the coexistence of two classes of states with strong mixing...
This contribution reports the final results of the IS541 experiment that searched for beta-delayed proton emission from 11Be through detection of the final state nucleus 10Be with accelerator mass spectrometry, coupled to a determination of the 11Be intensity via gamma decays. A first experiment (published 2014 [1]) reported an observation of the decay branch. In a follow-up experiment twelve...
