Session 14: Nuclear ground-state properties: new methods ans results
- Jan Jolie (IKP, Köln, Germany)
Storage of freshly produced secondary particles in a storage ring is a straightforward way to achieve the most efficient use of the rare species as it allows for using the same secondary ion multiple times. Employing storage rings for precision physics experiments with highly-charged ions (HCI) at the intersection of atomic, nuclear, plasma and astrophysics is a rapidly developing field of...
Transfer reactions at the high-precision Q3D spectrometer at the University of Munich have shown that there are many low-lying excited K=0+ states in well-deformed nuclei. Historically, 0+ states were difficult to measure and hindered testing and verification of numerous nuclear models due to the absence of the predicted and essential 0+ states. This entire process changed, since starting in...
One of the pillars for the study of exotic nuclides is the precise knowledge of the nuclear binding energy, which is directly and model-independently deduced from atomic-mass data. Tackling the increasing challenge to determine the mass of isotopes having low production yields and short half-lives, multi-reflection time-of-flight (MRTOF) mass spectrometry has grown from an initially...
Shape coexistence dominates the exotic structure and dynamics revealed by neutron-rich nuclei in the A=100 mass region. Sudden variations in the structural evolution with spin, excitation energy, and particle number, the occurrence of isomeric states, their decays and the exotic features of the daughter states represent various facets of shape coexistence and mixing. We addressed different...
A quadrupole-octupole axially symmetric geometric model is proposed for the description of alternate parity bands observed in heavy [1] and medium mass even-even nuclei [2]. The shapes and the dynamical behaviour of the considered nuclei are ascertained from the phenomenology of the adopted model and the obtained parameters [2,3]. The model parameters exhibit a regular evolution as a function...
