The rotational structure of 246Fm has been investigated using in-beam γ -ray spectroscopic techniques. The
experiment was performed using the JUROGAMII germanium detector array coupled to the gas-filled recoil
ion transport unit (RITU) and the gamma recoil electron alpha tagging (GREAT) focal plane detection system.
Nuclei of 246Fm were produced using a 186 MeV beam of 40Ar impinging on a 208Pb target. The JUROGAMII
array was fully instrumented with Tracking Numerical Treatment 2 Dubna (TNT2D) digital acquisition cards.
The use of digital electronics and a rotating target allowed for unprecedented beam intensities of up to 71
particle-nanoamperes for prompt γ -ray spectroscopy at a level of approximately 11 nb. With all these major
experimental advances a rotational band is observed in 246Fm.

Discovery of the new isotopes ²⁴⁰Es and ²³⁶Bk and in-beam spectroscopic studies of ²⁴⁴Cf
Konki, Joonas (University of Jyväskylä, 2017)The hitherto unknown neutron-deficient nuclei 240Es and 236Bk were synthesised using the fusion-evaporation reaction 209Bi(34S,3n)240Es. The ritu gas-filled recoil separator and the great spectrometer were used in this ... -
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 ... -
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 ... -

(Elsevier, 2023)This work aims at presenting an alternative approach to the long standing problem of the B(E2) values in Sn isotopes in the vicinity of the N=Z double-magic nucleus 100Sn, until now predominantly measured with relativistic ... -
Laser spectroscopy for nuclear structure physics
Campbell, P.; Moore, Iain; Pearson, M.R. (Elsevier B.V., 2016)High-resolution laser spectroscopy is an established powerful tool in the study of nuclear shape, size and multipole moments. Measurements of the hyperfine structures and isotope shifts in the atomic spectra of radioactive ...
