Neutron Knockout at Relativistic Energies across the Psd Shell
Paper in proceedings, 2009
One-neutron knockout reactions have been studied in a systematic way for a set of neutron-rich projectiles. The goal of the experiment, performed at GSI, was to explore the evolution of the nuclear structure close to the neutron drip line, in the region between C and Al. The momentum distributions of the surviving fragments and the cross-sections of the knockout process have been measured and used as physical observables. This report focuses on oxygen and nitrogen isotopes around N = 14. In particular, we discuss the Case Of N-12, for which the mentioned observables have been determined for the first time. We will consider O-23, already studied in earlier experiments, as a reference.
