Heavy ion reactions are studied making use of the PRISMA magnetic spectrometer coupled to a gamma detector array at the Laboratori Nazionali di Legnaro. By trajectory reconstruction, the reaction products are fully identified in mass, nuclear charge and kinetic energy, while coincident spectra of both binary partners are constructed after Doppler correction. Through the study of the motion of the ions in the spectrometer, which allows to correct for the aberrations induced by the transport of the reaction products in the magnetic fields, absolute differential cross sections are extracted for elastic scattering, inelastic excitation and one-nucleon transfers, also for specific excited states. Experimental data are compared with semi-classical calculations and Distorted Wave Born approximation predictions.
The work outlines an experimental method which can become valuable to extract structural information from heavy-ion reaction studies.
