The isomeric structure of the N=77 isotones 14265Tb and 14467Ho have been studied with the 92Mo(54Fe, xpn) fusion evaporation reaction at the University of Jyväskylä. The Jurospehere II germanium array was employed in conjunction with the RITU gas filled recoil separator. The feeding and decay of a 500(20) ns isomeric state in 144Ho has been established for the first time together with states built upon the known 15 μs isomer in 142Tb. The behavior of these new structures above the isomers suggest that they are low deformation configurations which display signs of triaxiality.

A fusion-evaporation reaction has been employed to search for isomeric states in the near-proton drip-line N577 isotones, 65 142Tb and 67 144Ho. The recoiling nuclei were implanted into a silicon detector at the focal ...

A projectile Coulomb-excitation experiment was performed at the radioactive ion beam facility HIE-ISOLDE at CERN. The radioactive 140Nd and 142Sm ions were post accelerated to the energy of 4.62 MeV/A and impinged on a ...
Mass Measurements of Proton-rich Nuclei with JYFLTRAP

Eronen, Tommi (Jagiellonian University, 2011)

The Penning trap setup JYFLTRAP, connected to the IGISOL facility, has been extensively used for atomic mass measurements of exotic nuclei. On the proton rich side of the chart of nuclei mass measurements have mostly ...

(American Physical Society (APS), 2023)

Three three-quasiparticle isomers, one at an excitation energy of 2.3 MeV with T1/2=0.48(4)μs, and two shorter-lived with unknown half-lives at slightly lower energies have been identified in 129Nd using the MARA + JUROGAM ...
