Advances in studies of nuclei far from stability
TL;DR: The results of recent experimental and theoretical investigations are presented and the new insights being gained are discussed in this article, where some of the highlights described include ground-state proton radioactivity, beta-delayed 2n, 3n and 2p decays, the coexistence of states built on quite different nuclear shapes in the same nucleus, new regions of strongly deformed nuclei, and the importance of the reinforcement of proton and neutron shell gaps on the shape of a nucleus.

In-beam γ-ray study of 189, 191, 193Au
TL;DR: In this paper, levels are established up to the 43 2 − and 43 2 + states in 193Au, and a 10 ns isomer of the h 9 2 proton state was found in 191Au.

Description of odd-A nuclei in the Pt region in the interacting boson-fermion model
Roelof Bijker,Ael Dieperink +1 more
TL;DR: In this article, the properties of unique parity states in odd-proton (77Ir, 79Au) and odd-neutron nuclei (78Pt) are investigated in the framework of the interacting boson-fermion approximation model.

On-line nuclear orientation of Au isotopes at KOOL
TL;DR: On-line low temperature nuclear orientation measurements were performed on shortlived Ni, Ni and Ni implanted in an iron matrix as discussed by the authors, where spin values of excited levels and mixing ratios of transitions in the daughter nuclei Pt and Au were presented.

Decays of 183Hg and 183Au
M. I. Macias-Marques,C. Bourgeois,P. Kilcher,B. Roussière,J. Sauvage,M. C. Abreu,M.G. Porquet +6 more
TL;DR: The β + /EC decays of 183 Hg and 183 Au have been studied on-line with mass-separated sources from the ISOCELE facility as mentioned in this paper, and a prolate shape for 183 Pt can be deduced from these results and there is good evidence to believe that the positive-parity states in odd- A gold isotopes correspond to oblate-shaped nuclei.

Collective model description of transitional odd-A nuclei: (I). The triaxial-rotor-plus-particle model
TL;DR: In this article, the energy spectrum of an odd nucleon coupled to a triaxial rotating core has been calculated as a function of the deformation β, the asymmetry γ and the Fermi energy λf.
