Session 2
- Maria Garcia Borge (CSIC Madrid)
This presentation will focus on the experiments carried out during 2017 with ISOLTRAP, the versatile mass spectrometer situated at ISOLDE/CERN. Highlights of this year's campaign were the precision mass measurements of neutron-rich krypton ($^{98,99}$Kr), argon ($^{48}$Ar) and cadmium ($^{127,129,131,132}$Cd) isotopes addressing, respectively, the onset of deformation in the $A \approx 100$...

The structure of nuclei in the vicinity of doubly magic $^{100}$Sn offer insight to the interplay between the seniority scheme in closed-shell nuclei and isoscalar proton-neutron interactions which are prevalent in $N \sim Z$ nuclei. Below $^{100}$Sn, information on the excited states of $N \sim Z$ nuclei is accessible by isomeric decays and...
The vibrational first $2^+$ and $3^-$ states of the doubly-magic nucleus $^{132}$Sn were excited via safe Coulomb excitation (CE) employing the recently commissioned HIE-ISOLDE accelerator at CERN in conjunction with the highly efficient MINIBALL array. The $^{132}$Sn ions were accelerated to an energy of 5.5 MeV/nucleon and impinged on a $^{206}$Pb target. Dexciting $\gamma$ rays from the...
With a proton hole in the Z = 50 shell closure, the indium isotopic chain (Z = 49) offers a
compelling scenario to explore the evolution of nuclear-structure properties in the
neighbourhood of the doubly-magic isotopes 100Sn (Z, N = 50) and 132Sn (N = 82).
This contribution will present recent measurements of the hyperfine spectra of the neutronrich
indium isotopes 113-131In using the...
