Nucleon transfer reactions in the 90Zr+208Pb system

Multinucleon transfer reactions have been studied in the 90Zr+208Pb system close to the Coulomb barrier energy in the Prisma + Clara set-up. Light binary partners have been detected in the Prisma magnetic spectrometer, while the coincident rays have been detected in the Clara -array. Trajectory reconstruction in the spectrometer provides the identification of the light fragments in their charge, mass and velocity. These allow, together with the coincidences with the Clara array, to attribute electromagnetic transitions and yields to each of the transfer channels. In the 90Zr+207Pb multinucleon transfer reactions, outgoing particles with the atomic number Z = 30-40 and mass number A = 60-94 were recognized. The level schemes of the presented isotopes have been constructed and updated based on systematics with neighbouring nuclei, and data from literature. In this thesis, we focused on spectra of Zr (together with their heavy partner, Pb), Y and Sr isotopic chains. Based on these observations, level schemes are constructed. In some cases, new rays were observed, and if possible, transitions were suggested.
