A new isomeric 0+ state was identified as the first excited state in the self-conjugate (N = Z) nucleus
72Kr. By combining for the first time conversion-electron and gamma-ray spectroscopy with the
production of metastable states in high-energy fragmentation, the electric-monopole decay of the new
isomer to the ground state was established. The new 0+ state is understood as the band head of the
known prolate rotational structure, which strongly supports the interpretation that 72Kr is one of the rare
nuclei having an oblate-deformed ground state. This observation gives in fact the first evidence for a
shape isomer in a N = Z nucleus.

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 ... -
