Heavy-ion transfer reactions studied at large internuclear distances with the PRISMA magnetic spectrometer

Abstract

We performed a study of the behaviour of the main transfer channels in the 116Sn+60Ni system at different bombarding energies from above to well below the Coulomb barrier. The experiment has been done in inverse kinematics, detecting the lighter target-like ions with the magnetic spectrometer PRISMA at very forward angles. Good mass, nuclear charge and kinetic energy resolutions have been achieved. Sufficient statistics has been accumulated to extract angular distributions for different bombarding energies, requiring a study of the response function of the spectrometer. The comparison between the data and microscopic calculations for the present case and for the previously measured 96Zr+40Ca system, namely superfluid and near closed shells nuclei, should significantly improve our understanding of nucleon-nucleon correlation properties in multinucleon transfer processes.
