Excited states in mirror nuclei 31S and 31P were populated in the 1n and 1p exit channels, respectively, of the reaction 20Ne + 12C. The beam of 20Ne, with an energy of 33 MeV, was delivered for the first time by the Piave-Alpi accelerator of the Laboratori Nazionali di Legnaro. Angular correlations of coincident pairs and Doppler-shift attenuation lifetime measurements in 31S and 31P were performed using the multidetector array GASP in conjunction with the EUCLIDES charged particle detector. A comparison of the determined B(E1) strengths of the analog mirror 7/2− → 5/2+ transitions indicates the presence of a violation of isospin symmetry.

Isospin-symmetry breaking in masses of N ≃ Z nuclei

Ba̧czyk, P.; Dobaczewski, Jacek; Konieczka, M.; Satuła, W.; Nakatsukasa, T.; Sato, K. (Elsevier B.V., 2018)

Effects of the isospin-symmetry breaking (ISB) beyond mean-field Coulomb terms are systematically studied in nuclear masses near the N = Z line. The Coulomb exchange contributions are calculated exactly. We use extended ...

(American Physical Society, 2024)

Lifetime measurements of low-lying excited states in the semimagic (N = 50) nucleus 95Rh have been performed by means of the fast-timing technique. The experiment was carried out using γ -ray detector arrays consisting of ...
Isovector and isoscalar spin-multipole giant resonances in the parent and daughter nuclei of double-β-decay triplets

Kauppinen, Elina; Suhonen, Jouni (American Physical Society, 2022)

The strength distributions, including giant resonances, of isovector and isoscalar spin-multipole transitions in the commonly studied double-β-decay triplets are computed in the framework of the quasiparticle random-phase ...
Mass measurements of neutron-deficient nuclei and their implications for astrophysics

Kankainen, Anu; Novikov, Yuri; Schatz, H.; Weber, Christine (Springer, 2012)

During the years 2005-2010 the double-Penning-trap mass spectrometer JYFLTRAP has been used to measure the masses of 90 ground and 8 isomeric states of neutron-deficient nuclides with a typical precision of better than ...
Nuclear mean-square charge radii of^{63,64,66,68-82}Ga nuclei: No anomalous behavior at N=32

(American Physical Society, 2012)

Collinear laser spectroscopy was performed on the 63,64,66,68−82Ga isotopes with neutron numbers from N = 32 to N = 51. These measurements were carried out at the ISOLDE radioactive ion beam facility at CERN. Here we present ...
