New Spins for ground states and isomers in Pd and Pd
Levels in 115Pd and 117Pd nuclei, populated in the spontaneous fission of 248Cm were studied by means of prompt gamma spectroscopy using the EUROGAM2 array of Anti-Compton spectrometers. Negative-parity, I = 9/2 excitations were identified, which are associated with the long-lived isomers in these nuclei, reported previously as 11/2- excitations. The new data indicate spin and parity 3/2 + for ground states in 115Pd and 117Pd instead of 5/2 + proposed in previous works. This result implicates changes of spin assignments to other levels in both nuclei

Production and identification of new, neutron-rich nuclei in the {sup 208}Pb region
The recently developed methods allowing the experimental studies on new neutron-rich nuclei beyond doubly-magic {sup 208}Pb are briefly described. An identification of new neutron-rich isotopes {sup 215}Pb and {sup 217}Bi, and new decay properties of {sup 216}Bi studied by means of a pulsed release element selective technique at PS Booster-ISOLDE are reported
Trap-assisted studies of odd, neutron-rich isotopes from Tc to Pd
We review the present and future of trap-assisted structure studies of
odd, neutron-rich Tc, Ru, Rh and Pd isotopes at the limits of present experimental techniques. These nuclei of refractory elements are produced in light-particle
induced fission and filtered by their mass number with the IGISOL mass separator.
Further mass separation with the JYFLTRAP Penning trap system provides a clean,
monoisotopic beam perfectly suited for precise nuclear spectroscopy. Connecting the
IGISOL and the JYFLTRAP facilities to the recently installed MCC30/15 cyclotron
opens new prospects for post-trap spectroscopy of very exotic, neutron-rich nuclei.peerReviewe
Production of beams of neutron-rich nuclei between Ca and Ni using the ion-guide technique
It was shown for the first time that quasi- and deep-inelastic reactions can be successfully incorporated into the conventional Ion-Guide Isotope Separator On-Line (IGISOL) technique. Yields of radioactive projectile-like species such as 62, 63Co are about 0.8ions/s/pnA corresponding to a total IGISOL efficiency of about 0.06%
