The ground-state rotational band of the neutron-deficient californium (

Cf
was identified for the first time and measured up to a tentative spin and parity of

. The observation of the rotational band indicates that the nucleus is deformed. The kinematic and dynamic moments of inertia were deduced from the measured
γ
-ray transition energies. The behavior of the dynamic moment of inertia revealed an up-bend due to a possible alignment of coupled nucleons in high-
j
orbitals starting at a rotational frequency of about

isotones as well as with available theoretical calculations that have been performed for nuclei in the region.

(American Physical Society, 2018)Lifetimes of the first excited 2 + and 4 + states in the extremely neutron-deficient nuclide 172 Pt have been measured for the first time using the recoil-distance Doppler shift and recoil-decay tagging ... -
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 ... -

(American Physical Society, 2020)The odd-Z 251Md nucleus was studied using combined γ-ray and conversion-electron in-beam spectroscopy. Besides the previously observed rotational band based on the [521]1/2− configuration, another rotational structure has ... -

(American Physical Society, 2018)Using fusion-evaporation reactions, a gas-filled recoil separator, recoil-gating technique and recoil-isomer decay tagging technique we have extended the level scheme of 203 At ( N = 118 ) significantly. We have ... -
Spectroscopic Properties of Nuclear Skyrme Energy Density Functionals
Tarpanov, D.; Dobaczewski, Jacek; Toivanen, Jussi; Carlsson, B. G. (American Physical Society, 2014)We address the question of how to improve the agreement between theoretical nuclear single-particle energies (SPEs) and observations. Empirically, in doubly magic nuclei, the SPEs can be deduced from spectroscopic properties ...
