Monoisotopic samples of exotic, neutron-rich 117Rh nuclei, produced in the proton-induced fission of 238U and separated using the IGISOL mass separator coupled to the JYFLTRAP Penning trap, were used to perform β and γ coincidence spectroscopy of 117Pd. The spin parity of the ground state of 117Pd was determined to be 1/2+ and the 19.1 ms isomer at 203.2 keV was assigned a spin-parity 7/2−. The 117Rh β−-decay scheme was considerably extended, and various sequences of the levels were interpreted as resulting from the prolate, oblate, and triaxial nuclear shapes. Some of the β− decays were considered as the allowed Gamow-Teller transitions. The experimental distribution of Gamow-Teller strength is discussed.

Impact of Nuclear Deformation and Pairing on the Charge Radii of Palladium Isotopes

Geldhof, S.; Kortelainen, M.; Beliuskina, O.; Campbell, P.; Caceres, L.; Cañete, L.; Cheal, B.; Chrysalidis, K.; Devlin, C. S.; de Groote, R. P.; de Roubin, A.; Eronen, T.; Ge, Z.; Gins, W.; Koszorus, A.; Kujanpää, S.; Nesterenko, D.; Ortiz-Cortes, A.; Pohjalainen, I.; Moore, I. D.; Raggio, A.; Reponen, M.; Romero, J.; Sommer, F. (American Physical Society (APS), 2022)

The impact of nuclear deformation can been seen in the systematics of nuclear charge radii, with radii generally expanding with increasing deformation. In this Letter, we present a detailed analysis of the precise relationship ...

(Elsevier, 2024)

Reduced transition probabilities have been extracted between excited, yrast states in the 𝑁=𝑍+2 nucleus 94Pd. The transitions of interest were observed following decays of the 𝐼𝜋=14+, 𝐸𝑥=2129-keV isomeric state, which ...
Measurement and microscopic description of odd-even staggering of charge radii of exotic copper isotopes

de Groote, R. P.; Billowes, J.; Binnersley, C. L.; Bissell, M. L.; Cocolios, T. E.; Day Goodacre, T.; Farooq-Smith, G. J.; Fedorov, D. V.; Flanagan, K. T.; Franchoo, S.; Garcia Ruiz, R. F.; Gins, W.; Holt, J. D.; Koszorús, Á.; Lynch, K. M.; Miyagi, T.; Nazarewicz, W.; Neyens, G.; Reinhard, P.-G.; Rothe, S.; Stroke, H. H.; Vernon, A. R.; Wendt, K. D. A.; Wilkins, S. G.; Xu, Z. Y.; Yang, X. F. (Nature Publishing Group, 2020)

Nuclear charge radii globally scale with atomic mass number A as A1∕3, and isotopes with an odd number of neutrons are usually slightly smaller in size than their even-neutron neighbours. This odd-even staggering, ubiquitous ...
