An in-beam study has been performed to further investigate the known isomeric decays and to identify
T = 1 excited states in the medium-heavy N = Z = 33 nucleus 66As. The fusion-evaporation reaction 40Ca(28Si,pn)
66As was employed at beam energies of 75 and 83 MeV. The half-lives and ordering of two
known isomeric states in 66As have been determined with improved accuracy. In addition, several prompt γ -ray
transitions from excited states, both bypassing and decaying to the isomeric states in 66As, have been observed.
Most importantly, candidates for the 4+ → 2+ and 6+ → 4+ transitions in the T = 1 band have been identified.
The results are compared with shell-model calculations using the modern JUN45 interaction in the pf5/2g9/2
model space.

Spectroscopy of [sub 199,201]At
Auranen, Kalle (University of Jyväskylä, 2015)The excited states of 199At and 201At were studied using fusion evaporation reactions, a gas-filled recoil separator and various tagging methods. The level scheme of 201At was extended a lot including a cascade of magnetic ... -

Theoretical predictions of wimp-nucleus and neutrino-nucleus scattering in context of dark matter direct detection
Pirinen, Pekka (University of Jyväskylä, 2018)The nature of dark matter is at present an open question. Assuming the main component of dark matter consists of weakly interacting massive particles (WIMPs), directly detecting such particle via a scattering process ... -
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 ...
