  An approach to identify medium-mass ejectiles from peripheral heavy-ion
reactions in the energy region of 15 MeV/nucleon is developed for data obtained
with a large acceptance magnetic spectrometer. This spectrometer is equipped
with a focal plane multidetector, providing position, angle, energy loss and
residual energy of the ions along with measurement of the time-of-flight. Ion
trajectory reconstruction is performed at high order and ion mass is obtained
with a resolution of better than 1/150. For the unambiguous particle
identification however, the reconstruction of both the atomic number Z and the
ionic charge q of the ions is critical and it is suggested, within this work,
to be performed prior to mass identification. The new proposed method was
successfully applied to MAGNEX spectrometer data, for identifying neutron-rich
ejectiles related to multinucleon transfer generated in the 70Zn+ 64Ni
collision at 15 MeV/nucleon. This approach opens up the possibility of
employing heavy-ion reactions with medium-mass beams below the Fermi energy
(i.e., in the region 15-25 MeV/nucleon) in conjunction with large acceptance
ray tracing spectrometers, first, to study the mechanism(s) of nucleon transfer
in these reactions and, second, to produce and study very neutron-rich or even
new nuclides in previously unexplored regions of the nuclear landscape.
