Three-body model for the analysis of quasifree scattering reactions in inverse kinematics

A new method to calculate cross sections for (p,pn) and (p,2p) reactions measured under inverse kinematics conditions is proposed. The method uses the prior form of the scattering transition amplitude and replaces the exact three-body wave function appearing in this expression with an expansion in terms of p-n or p-p states, covering the physically relevant excitation energies and partial waves. A procedure of discretization, similar to that used in continuum-discretized coupled-channels calculations, is applied to make this expansion finite and numerically tractable. The proposed formalism is nonrelativistic, but several relativistic kinematical corrections are applied to extend its applicability to energies of current interest. The underlying optical potentials for the entrance and exit channels are generated microscopically by folding an effective density-dependent G matrix with the density of the composite nucleus. Numerical calculations for 12 C(p,2p), 12 C(p,pn), and 23 O(p,pn) at ∼400 MeV/nucleon are presented to illustrate the method. The role of final-state interactions and Pauli principle between the outgoing nucleons is also discussed.

“…In particular, since their first exploratory application to the phosphorus isotopes, in [1], single-nucleon knockout experiments with gamma-ray detection capability have been extensively tested and are being exploited to study the single-nucleon spectroscopy of exotic light [4,[8][9][10][11][12][13] and more medium-mass nuclei [14][15][16]. They are currently being used to study both the relative and absolute single-nucleon spectroscopy of neutron-and proton-rich nuclei [10,[14][15][16][17].…”

Correlated two-nucleon stripping reactions

The cross sections for the stripping of two correlated nucleons from light and medium-mass nuclei are considered. Such reactions are of interest both as a means for populating and identifying low-lying excited states of very exotic nuclear species and as a potential direct spectroscopic probe of two-nucleon correlations in such systems. A calculation scheme that combines the full shell model two-nucleon spectroscopic amplitudes with eikonal reaction theory is presented. The theoretical predictions of the method, and of more approximate schemes, are compared with new data on two-proton removal from 28 Mg. The combined full shell model structure amplitudes and reaction dynamics predictions are in good agreement with the available measurements. First indications of the sensitivity of the reaction mechanism to the spatial and angular momentum structure of the stripped two-nucleon wave functions are also discussed and clarified.

“…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

et al. 2008

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.
