Nuclear isomers purification via narrow-band
laser ionization from radioactive ion beams at
CERN, ISOLDE.
Relatore: Simone Casci, KU Leuven

With their anomalously long lifetime, nuclear isomers unique excited states in nuclei that can
give access to original research in nuclear physics and manipulation for applications in energy
storage [1], timekeeping [2] and medical imaging [3]. This seminar will discuss the production of
radioactive ion beams at the ISOLDE facility in CERN (Geneva, Switzerland). The isomer
purification process will be explained by introducing the collinear resonance ionization
technique performed at the CRIS experiment [4], together with the implementation of a decay
station for measuring unique nuclear structures made accessible by isomeric decays [5].
Experimental opportunities in isomeric decay spectroscopy, which would help to test the
predictive power of the nuclear shell model, will be presented through the example of neutronrich
Zn isotopes [6].
