The availability in the future of the LINAG accelerator at GANIL will offer a unique opportunity of high intensity stable ions beams that could be used to produce neutron rich nuclei in multi-nucleon transfer and deep inelastic reactions. At the energies available from LINAG, the production of exotic nuclei selected at 0° with respect to the beam direction from this type of reactions is poorly known.
To shed a light on this topic an experiment was performed recently at GANIL using VAMOS and EXOGAM spectrometers to measure the production of neutron-rich nuclei produced with a 10 MeV/A 48Ca beam impinging a 0.1 mg/cm2 thin 238U target. VAMOS allowed the selection and identification of the beam like ejectils and EXOGAM, in coincidence with VAMOS, gives spectroscopic information about the nuclei produced. We performed measurements at different values for the VAMOS magnetic rigidity and angle, 0° included, allowing a full overview of the exotic species produced. The energy in the centre of mass for the reactions is 1.7 times the coulomb barrier. Considering that the typical energy in the centre of mass used in “deep-inelastic” experiments is around 1.1 times the Coulomb barrier, our experimental cross-sections can be directly compared with well-known results from deep-inelastic experiments at grazing angle. The preliminary results will be presented.
