One and two-neutron transfer reactions with very heavy ions

The one and two-neutron transfer reactions with 637 MeV ¹¹⁶Sn and 270 Mev and 345 MeV ⁵⁸Ni beams on the rare earth ¹⁶¹Dy and ¹⁶²Dy targets, 325 MeV ⁵⁸Ni beam on the actinide target, and 570 MeV ¹¹²Sn on the spherical nuclei ¹¹⁷Sn and ¹¹⁸Sn targets were measured. These measurements were performed at Oak Ridge National Laborotary using the Tandem, Cyclotron and the Spin Spectrometer.

The particle-particle-γ coincidence methold was employed to identify the reaction exit channels; the Spin Spectrometer provided the γ-ray total energy and multiplicity to identify reaction entry channels.

In the present work, the cross sections and probabilities for one and two-neutron transfer reactions were measured; the transfer mechanism and nuclear struc ture effects are discussed.
