One-neutron knockout reactions have been used in this work to explore the evolution of the nuclear structure close to the neutron drip-line, where the neutron excess and the low binding energies can lead to important structural changes. This is the case for neutron halo configurations, the dissappearence of the N = 8 closed shell in 11Li or 12Be and the appearence of new sub-shell closures at N = 14 and 16 for oxygen isotopes, and the so-called island of inversion at N ~ 20.
Using the FRS spectrometer at GSI (Darmstadt, Germany), the longitudinal-momentum distributions of the emerging knockout fragments were measured along with the one-neutron removal cross-sections. The setup also included a set of Ge detectors (MINIBALL), which allowed to disentangle for a few cases the different states of the fragment populated in the one-neutron knockout reactions.
Thirty‐eight 
different 
isotopes,
 ranging 
from 
C to 
Al, 
were 
studied 
and 
the 
region 
between 
N
  8
 and
 22 
was 
closely 
examined. 
Particular
 attention
 has
 been 
paid to 
the C,
 N, 
F, 
O 
and 
Ne 
isotopic 
chains.
