A new pixel-structure detector array with a large solid angle coverage has been used for the first time to study the elastic scattering of exotic 17F nuclei from a 208pb target at 90.4 MeV.

These quantities have been compared with those obtained for the system 19F +208Pb at the same energy in the center of mass frame. The 17F+208Pb reaction cross section is more similar to those of the systems 16,17O+208Pb rather than to the one of the system 19F+208Pb at similar energies: this indicates that in the energy range around the Coulomb barrier the breakup channel is still weak. The exclusive breakup cross section 17F→16O+p has been measured for the first time at energy below the Coulomb barrier.

Abstract
A new pixel-structure detector array with a large solid angle coverage has been used for the first time to study the elastic scattering of exotic 17F nuclei from a 208pb target at 90.4 MeV. The experimental data have been analyzed in the framework of the optical model potential and the real and imaginary strong absorption radii have been evaluated. These quantities have been compared with those obtained for the system 19F +208Pb at the same energy in the center of mass frame. The 17F+208Pb reaction cross section is more similar to those of the systems 16,17O+208Pb rather than to the one of the system 19F+208Pb at similar energies: this indicates that in the energy range around the Coulomb barrier the breakup channel is still weak. The exclusive breakup cross section 17F→16O+p has been measured for the first time at energy below the Coulomb barrier.
