The α decay of 188,192Po has been reexamined in order to probe the 0+ states in the daughter nuclei 184,188Pb that can be associated with coexisting spherical, oblate, and∕or prolate configurations. Improved values were measured for the excitation energy and the feeding α-decay intensity of the 0+2state in 184,188Pb and conflicting results on the 0+3 state in 188Pb were clarified. All known cases of fine structure in the α decay of the even-even Po nuclei are reviewed. The reduced α-decay width systematics combined with potential-energy-surface calculations confirm the onset of deformation in the ground state of the polonium nuclei around the neutron midshell. An isomeric state with a half-life of 580(100)ns has been identified in 192Po.

Van; Beeke, O.; Dodson, B.; Scholey, Catherine; O’Donell, D.; Jakobsson, Ulrika; Grahn, Tuomas; Greenlees, Paul; Jones, Peter; Julin, Rauno; Khan, S.; Leino, Matti; Leppänen, Ari-Pekka; Eeckhaudt, Sarah; Mäntyniemi, K.; Pakarinen, Janne; Peura, Pauli; Rahkila, Panu; Sarén, Jan; Sorri, Juha; Uusitalo, Juha; Venhart, M. (American Physical Society, 2018)Excited states above the 17+ isomeric state in the proton-rich nucleus 152Tm were established by employing the recoil-isomer tagging technique. Data were collected using the JUROGAM gamma-ray array and the GREAT spectrometer ... -
Structure of 115Ag studied by β− decays of 115Pd and 115mPd
Rissanen, Juho; Kurpeta, Jan; Elomaa, Viki-Veikko; Eronen, Tommi; Hakala, Jani; Jokinen, Ari; Kankainen, Anu; Moore, Iain; Penttilä, Heikki; Plochocki, A.; Saastamoinen, Antti; Urban, W.; Weber, Christine; Äystö, Juha (American Physical Society, 2012)The excited levels of 115Ag have been studied via the beta decay of 115Pd and 115Pdm. The beta-decay schemes for both states have been considerably extended, especially the scheme following the decay of 115Pdm which ... -

(American Physical Society, 2020)Accurate mass measurements of neutron-rich iron and cobalt isotopes 67Fe and 69,70Co have been realized with the JYFLTRAP double Penning-trap mass spectrometer. With novel ion-manipulation techniques, the masses of the ... -
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 ... -
Ion traps in nuclear physics : recent results and achievements
Eronen, Tommi; Kankainen, Anu; Äystö, Juha (Pergamon, 2016)Ion traps offer a way to determine nuclear binding energies through atomic mass measurements with a high accuracy and they are routinely used to provide isotopically or even isomerically pure beams of short-living ions for ...
