Knockout reactions with heavy ion targets in inverse kinematics, as well as "quasi-free" (p,2p) and (p,pn) reactions are useful tools for nuclear spectroscopy. We report calculations on ab-initio many-body wavefunctions based on the no-core shell model to study the nucleon removal reactions in light nuclei, including beryllium, carbon, and oxygen isotopic chains, and explore the importance of using an ab-initio method. Our study helps clarifying how the extraction of spectroscopic factors from the experiments depend on the details of the many-body wavefunctions being probed. We show that recent advances with the ab-initio method can provide more insights on the spectroscopy information extracted from experiments.

“…At present, multiple reaction models have been used to describe the (p, pN) process: the distorted-wave impulse approximation (DWIA) was extensively used in the 1960s and 1970s [15,16] and has recently been revisited in quantummechanical [3,17] and eikonal [1,4,18] descriptions. The Faddeev-Alt-Grassberger-Sandhas (Faddeev-AGS) [2,[19][20][21] and transfer-to-the-continuum [22][23][24] formalisms have also been employed for the description of (p, pN) reactions, using very different descriptions to the DWIA approach. Given the variety of descriptions of the (p, pN) reaction, benchmarks between the different formalisms provide a useful assessment of their validity and limitations.…”

Background: Nucleon-knockout reactions on proton targets (p, pN) have experienced a renewed interest due to the availability of inverse-kinematics experiments with exotic nuclei. Various theoretical descriptions have been used to describe these reactions, such as the distorted-wave impulse approximation, the Faddeev-type formalism, and the transfer-to-the-continuum method. Purpose: Our goal is to benchmark the observables computed with the Faddeev and transfer-to-the-continuum formalisms in the intermediate energy regime relevant for the experimental (p, pn) and (p, 2p) studies. Method:We analyze the 11 Be(p, pn) 10 Be reaction for different beam energies, binding energies, and orbital quantum numbers with both formalisms to assess their agreement for different observables. Results: We obtain a good agreement in all cases considered, within ≈10%, when the input potentials are taken consistently and realistically. Conclusions: The results of this work prove the consistency and accuracy of both methods, setting an indication on the degree of systematic uncertainties applicable when using them to extract spectroscopic information from (p, pN) reactions.
