Effect of the 18O nuclear density on the nuclear potentials of the 18O+58,60Ni systems Original Research Article

Quasi-elastic, inelastic, one- and two-neutron transfer differential cross sections have been measured for the 18O+58,60Ni systems at sub-barrier energies. The corresponding bare potentials have been determined at interaction distances larger than the respective barrier radii, and the results have been compared with those previously obtained for systems involving the 16O as projectile. The detected difference between the 18O and 16O nuclear potentials has allowed the determination of the nuclear density that corresponds to the two extra neutrons of the 18O nucleus.
