Excited states in the 70Kr and 70Br nuclei were populated via the 40Ca(32S, 2n) 70Kr and 40Ca(32S, pn) 70Br fusion-evaporation reactions at the Accelerator Laboratory of the University of Jyväskylä. The 2+ −→ 0+ and 4+ −→ 2+ transitions in 70Kr have been found to be 881(1) keV and (tentatively) 1037(2) keV, respectively. Several new γ -ray transitions were also identified in 70Br, and the T = 1 band has been tentatively extended up to Jπ = 10+. The newly observed transitions in 70Kr and 70Br resolve discrepancies in the previously reported results for these nuclei. The experimental Coulomb, triplet, and mirror energy differences are compared with the results of two independent shell-model calculations. The comparisons aim to investigate the shape evolution and the role of the isospin breaking interactions in this mass region.

(Elsevier, 2023)

Excited states in the Tz = 0, −1 nuclei 62Ga and 62Ge were populated in direct reactions of relativistic radioactive ion beams at the RIBF. Coincident γ rays were measured with the DALI2+ array and uniquely assigned to the ...
Isospin triplet A=14 : search for states with enhanced radii

Demyanova, A. S.; Danilov, A. N.; Ogloblin, A. A.; Starastsin, V. I.; Dmitriev, S. V.; Leonova, T. I.; Goncharov, S. A.; Belyaeva, T. L.; Trzaska, W. H.; Gurov, Y. B. (IOP Publishing Ltd, 2020)

This article is devoted to study of isobar-Analogue states 1- in triplet A=14: 14C-14N-14O. Previously signs of neutron halo in the 1-, 6.09 MeV state of 14C were obtained by two independent groups. In this article we ...

Electric quadrupole matrix elements, Mp, for the Jπ=2+→0+, ΔT=0, T=1 transitions across the A=46 isobaric multiplet 46Cr-46V-46Ti have been measured at GSI with the FRS-LYCCA-AGATA setup. This allows direct insight into ...
Isospin-symmetry breaking in masses of N ≃ Z nuclei
