FI: COULOMB-EXCITATION EXPERIMENTS WITH THE Q3D SPECTROMETER AT MLL - MAGDALENA ZIELINSKA 
 ELENCO COMPLETO 

DATA: 10-04-2019

SEZIONE DI FIRENZE
Coulomb excitation is a well-established method to investigate electromagnetic properties of low-lying excited states in atomic nuclei. The measured excitation cross sections can be directly related to E2 and E3 transition strengths, as well as to quadrupole moments of short-lived excited states, without any nuclear-model assumptions required. The first Coulomb-excitation experiments were performed in the 1950s, employing only particle spectroscopy. The advent of high-resolution gamma-ray spectroscopy in the 1970s enabled complex multi-step Coulomb-excitation studies of deformed nuclei, and the possibility to perform Coulomb-excitation experiments without gamma-ray detection has almost been forgotten. They still represent, however, an interesting alternative to the more popular gamma-particle coincidence measurements, especially for nuclei with low level density. In the seminar I will present very preliminary results of our recent experimental campaign with the Q3D magnetic spectrometer at Meier-Leibnitz Laboratory in Munich, with a focus on octupole collectivity in Zr isotopes.
