Experimental studies of unbound neutron-rich nuclei

Abstract

The three-body description of two-neutron halo nuclei relies on the two-body interactions between the constituents. In order to provide constraints on calculations devoted to $^{14}$Be and $^{17}$B, neutron unbound states of $^{13}$Be and $^{16}$B have been investigated by one-proton knockout. The experimental techniques and results are discussed here.Comment: 9 pages, 3 figures. Invited contribution to "Critcal Stability III", ECT*, Trento, Italy, September 2003.
