Multinucleon transfer reactions in closed-shell nuclei

Multinucleon transfer reactions in $^{; ; ; ; 40}; ; ; ; $Ca$+^{; ; ; ; 96}; ; ; ; $Zr and $^{; ; ; ; 90}; ; ; ; $Zr$+^{; ; ; ; 208}; ; ; ; $Pb 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 $^{; ; ; ; 95}; ; ; ; $Zr populated in one particle transfer channels are discussed in terms of particle-phonon couplings. The $\gamma$ decays from states in $^{; ; ; ; 42}; ; ; ; $Ca in the excitation energy region expected from pairing vibrations are also observed.
