Szanowni Państwo,
w związku z tym, że seminarium 2 maja 2019 r. nie odbędzie się ze względu na święta 1 i 3 maja br. serdecznie zapraszamy na seminarium do ŚLCJ UW, które odbędzie się 26 kwietnia 2019 r. (piątek) o godz. 11:00 w budynku ŚLCJ UW przy ul. Pasteura 5a, na którym:
dr Magda Zielińska (IRFU/DPhN, CEA, Universite Paris-Saclay, Gif-sur-Yvette, Francja)
wygłosi referat pt.:
„Coulomb-excitation experiments with the Q3D spectrometer at MLL”
Abstract: 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 and implications of the remeasurement of the B(E2; 2+1 -> 0+1) value in 104Pd for exotic-beam studies at ISOLDE.
