The α -decay branch of the πh 11 / 2 isomer in 164 Ir has been identified using the GREAT spectrometer. The 164 Ir nuclei were produced using the 92 Mo( 78 Kr ,p 5 n ) 164 Ir reaction and separated in flight using the recoil ion transport unit (RITU) gas-filled separator. The measured α -decay energy of 6880 ± 10 keV allowed the excitation of the πh 11 / 2 state in 160 Re to be deduced as 166 ± 14 keV. The half-life of 164 Ir was measured with improved precision to be 70 ± 10 μ sandan α -decay branching ratio of 4 ± 2% was determined. Improved half-life and branching ratio measurements were also obtained for 165 Ir, but no evidence was found for the ground-state decays of either 164 Ir or 165 Ir.

Production and investigation of neutron-rich Osmium isotopes with and around N=126 using gas flow transport method

Novikov, K.; Kozulin, E. M.; Harca, I. M.; Dmitriev, S.; Flueras, A.; Greenlees, Paul; Hanappe, F.; Khlebnikov, S. V.; Loktev, T.; Maurer, J.; Nitto, A.

Neutron-rich isotopes of heavy nuclei are until now poorly studied. In this work we investigate neutron-rich osmium isotopes produced in multi-nucleon transfer reactions. The reaction 136Xe+208Pb at energy near Coulomb ...
Precision measurement of the magnetic octupole moment in 45Sc as a test for state-of-the-art atomic- and nuclear-structure theory

de Groote, R.P.; Moreno, J.; Dobaczewsk,i J.; Koszorús, Á.; Moore, I.; Reponen, M.; Sahoo, B.K.; Yuan, C. (Elsevier BV, 2022)

We report on measurements of the hyperfine A, B and C -constants of the 3d4s2 2 D5/2 and 3d4s2 2 D3/2 atomic states in 45Sc. High-precision atomic calculations of the hyperfine fields of these states and second-order ...

The nucleus 203Fr has been studied through γ -ray and electron spectroscopy, using the recoil-decay tagging technique. A 13/2+ state, with a half-life of 0.37(5) μs, has been observed in 203Fr. Both the α-decay branch ...

(American Physical Society, 2014)

The recoil-β tagging technique was used to identify transitions associated with the decay of the 2+ and, tentatively, the 4+ excited states in 74Sr. Combining these results with published data for the A = 74 isobars, triplet ...

Rotational structures have been measured using the Jurogam II and GAMMASPHERE arrays at low spin following the 155Gd(α,2n)157Dy and 148Nd(12C,5n)155Dy reactions at 25 and 65 MeV, respectively. We report high-K bands, which ...
