Key in the establishment of the traditional concepts of nuclear shells, binding-energy studies were also pivotal to the early realization of the demise of the traditional shell closures away from stability [1]. Extensive effort has followed to examine the classical signatures for magicity in exotic nuclei and more than three decades later, the robustness of all major shell closures has been...

45. Standard Model tests in nuclei

Martin Gonzalez-Alonso (CERN)

Invited

I will discuss which kind of new phenomena can be probed through precision measurements in nuclear processes. Using a model-independent description I will discuss the interplay between the different experiments and which ones are the most sensitive and promising. Finally I will analyze the synergy with searches at high-energy colliders, such as the LHC, and with other electroweak precision observables.

Extracting the shape of a nucleus in its ground state when its spin is less than 1 is not possible by a direct measurement of the quadrupole moment. This limits the sources of information available for the study of the ground state shapes of even-even nuclei. Common alternatives are the extraction of the information from electromagnetic transitions along the ground state band or measurements...

15. Beta-delayed fission investigation of $^{188m1,m2}$Bi employing isomer-selective laser ionization

A dedicated and world-wide unique program to study $\beta$-delayed fission ($\beta$DF) is being performed by our collaboration since a decade ago at the ISOLDE (CERN), e.g. [1,2,3]. In $\beta$DF, the mother nucleus undergoes $\beta$ decay to excited state in the daughter nucleus with the energy comparable to the fission barrier height and the daughter nucleus then fissions. The excitation...
