Excited states of 90,92,94Y populated in 90Zr+208Pb multinucleon transfer reaction

Abstract

Multinucleon transfer reactions in $^{90}$Zr+$^{208}$Pb have been studied via fragment-$\gamma$ coincidences, employing the PRISMA magnetic spectrometer coupled to the CLARA $\gamma$-array. An analysis on Y isotopes has been carried out incorporating spectroscopic as well as reaction mechanism aspects. New $\gamma$ transitions have been observed in $^{94}$Y, confirming the findings of recent studies where nuclei were produced via fission of uranium, and a comparison with near-by $^{90,92}$Y 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.
