Abstract

Multinucleon transfer reactions in 90Zr+208Pb have been studied via fragment-γ coincidences, employing the PRISMA magnetic spectrometer coupled to the CLARA γ-array. An analysis on Y isotopes has been carried out incorporating spectroscopic as well as reaction mechanism aspects. New γ transitions have been observed in 94Y, confirming the findings of recent studies where nuclei were produced via fission of uranium, and a comparison with near-by 90,92Y isotopes populated in the same reaction has been discussed. Experimental cross sections have been extracted and compared with the GRAZING calculations, showing a fair agreement along the neutron pick-up side. The results confirm how multinucleon transfer reactions are a suitable mechanism for the study of neutron-rich nuclei.
