“…This level of agreement likely reflects the accuracy in applying the eikonal model, specifically the underlying assumption that the A ¼ 9 cores are spectators to the removal mechanism, to such an extreme case of deeply bound neutrons. The discrepancy between VMC and NCSM spectroscopic factors increases from 20% in h 10 Bej 9 Be þ ni to nearly 50% for h 10 Cj 9 C þ ni indicating that continuum effects, neglected in the NCSM, may also play an important role. This will be investigated in the future with the NCSM/RGM formalism [31].…”

“…Knockout reactions have their foundations in the study of p-shell nuclei, used previously to investigate properties of weakly bound halo nuclei [8][9][10][11] and determine spectroscopic factors [12,13]. These reactions have since been extended to heavier mass systems demonstrating sensitivity to single-particle structure for short-lived nuclei available at beam rates of only a few ions per second [14][15][16][17].…”

“…Beams of 10 Be and 10 C were produced at the National Superconducting Laboratory's Coupled Cyclotron Facility through projectile fragmentation of a 150 MeV=u beam of 16 O incident on a 9 Be production target and were separated from additional reaction products using the A1900 fragment separator [18]. Secondary beams with energies of either 80 or 120 MeV=u were then delivered to the experimental area and impinged secondary reaction targets of either 376ð4Þ mg=cm 2 9 Be or 403ð5Þ mg=cm 2 nat C PRL 106, 162502 (2011) P…”

“…In addition to the study of the structure of halo nuclei [4,5] and the search for the breakdown of shell closures for nuclei in the regime of extreme N / Z [6], spectroscopic factors for individual single-particle states have been deduced using this experimental approach [7][8][9][10].…”

One-neutron knockout reactions from the deeply bound N = 16 isotones with Z = 16, 17, and 18 have been studied in inverse kinematics with intermediate-energy beams. ␥-ray spectroscopy in coincidence with the detection of knockout residues allowed for an investigation of the one-neutron removal leading to individual excited states. Spectroscopic factors are deduced in the framework of the sudden and eikonal approximations and are compared to USD shell-model predictions. The momentum distributions observed in the experiment are used to identify the angular momentum l carried by the knockedout neutron by comparing with calculations based on a black-disk reaction model. The systematics of reduced single-particle occupancies attributed to the effect of short-range correlations, observed so far for stable and near-magic nuclei in ͑e , eЈp͒ and ͑d , 3 He͒ reactions and in one-nucleon knockout on light deeply bound systems, are extended in this work.

“…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].…”

Reduction of spectroscopic strength: Weakly-bound and strongly-bound single-particle states studied using one-nucleon knockout reactions

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.
