“…A 188(4)-mg/cm 2 -thick 9 Be knockout target was placed at the reaction target position of the S800 spectrograph [29] and surrounded by SeGA (Segmented Germanium Array), a highly segmented germanium detector array optimized for in-beam γ -ray spectroscopy with fast exotic beams [30]. Its high degree of segmentation allows an accurate event-by-event Doppler reconstruction of the γ rays emitted by the reaction residues in-flight, where the emission angle entering the Doppler reconstruction is derived from the location of the detector segment that registered the largest energy deposition.…”

“…For each reaction, the inclusive cross sections for the one-nucleon knockout to all bound final states, σ inc , is determined from the yield of detected knockout residues divided by the number of incoming projectiles relative to the number density of the 9 Be knockout target. A detailed discussion of the cross sections, the residue momentum distributions, and the experimentally deduced spectroscopic strengths will be presented in Sec.…”

“…The reactions 9 Be( 28 S, 27 P)X and 9 Be( 24 Si, 23 Al)X are used to probe the weakly bound proton states and the reactions 9 Be( 28 S, 27 S)X and 9 Be( 24 Si, 23 Si)X to probe the strongly bound neutron states. These reactions are particularly well suited because (i) weakly and strongly bound states are probed in the same nucleus and (ii) the knockout residues are located close to the proton drip line and have only one or at most two final states bound against proton emission.…”

“…First employed to study halo systems [8][9][10], subsequent analyses have used this experimental approach to deduce spectroscopic factors of individual single-particle states in many cases [5,[11][12][13][14][15][16]. In so doing, nucleon knockout reactions have contributed to the clarification of the evolution of shell structure toward the nucleon drip lines, helping to unravel the disappearance of familiar magic numbers and the formation of new shell gaps in nuclei with extreme N : Z ratios [17][18][19][20][21][22].…”

Both one-proton and one-neutron knockout reactions were performed with fast beams of two asymmetric, neutron-deficient rare isotopes produced by projectile fragmentation. The reactions are used to probe the nucleon spectroscopic strengths at both the weakly and strongly bound nucleon Fermi surfaces. The one-proton knockout reactions 9 Be( 28 S, 27 P)X and 9 Be( 24 Si, 23 Al)X probe the weakly bound valence proton states and the one-neutron knockout reactions and 9 Be( 28 S, 27 S)X and 9 Be( 24 Si, 23 Si)X the strongly bound neutron states in the two systems. The spectroscopic strengths are extracted from the measured cross sections by comparisons with an eikonal reaction theory. The reduction of the experimentally deduced spectroscopic strengths, relative to the predictions of shell-model calculations, is of order 0.8-0.9 in the removal of weakly bound protons and 0.3-0.4 in the knockout of the strongly bound neutrons. These results support previous studies at the extremes of nuclear binding and provide further evidence that in asymmetric nuclear systems the nucleons of the deficient species, at the more-bound Fermi surface are more strongly correlated than those of the more weakly bound excess species.
