Multinucleon transfer reactions in closed-shell nuclei

Multinucleon transfer reactions in Ca-40+Zr-96 and Zr-90+Pb-208 have been measured at energies close to the Coulomb barrier in a high-resolution gamma-particle coincidence experiment. The large-solid-angle magnetic spectrometer PRISMA coupled to the CLARA gamma array has been employed. Trajectory reconstruction has been applied for the complete identification of transfer products. Mass and charge yields, total kinetic energy losses, gamma transitions of the binary reaction partners, and comparison of data with semiclassical calculations are reported. Specific transitions in Zr-95 populated in one-particle transfer channels are discussed in terms of particle-phonon couplings. The gamma decays from states in Ca-42 in the excitation energy region expected from pairing vibrations are also observed.
