“…Nucleon knockout reactions induced by beryllium or carbon targets are the most commonly used reactions. The measured nuclear removal cross-section was interpreted as the sum of two contributions: (i) inelastic breakup, where the removed nucleon is absorbed by the target (also called stripping or knockout) and (ii) elastic breakup (also called diffraction dissociation) [5][6][7][8][9][10][11][12][13]. The assumption about absorption by the target was made despite the fact that the fate of the ejected nucleon was not traced either in the experiments or in the theoretical models used in the analysis of the experimental data.…”

Nucleon knockout experiments using beryllium or carbon targets reveal a strong dependence of the quenching factors, i.e., the ratio ($$\hbox {R}_{\textrm{s}}$$ R s ) of theoretical to the experimental spectroscopic factors ($$\hbox {C}^2{\textrm{S}}$$ C 2 S ), on the proton-neutron asymmetry in the nucleus under study. However, this dependence is greatly reduced when a hydrogen target is used. To understand this phenomenon, exclusive $$^{1}\text {H}(^{17}\text {Ne},$$ 1 H ( 17 Ne , $$2\hbox {p}~^{16}\text {F})$$ 2 p 16 F ) and inclusive $$^{12}\text {C}(^{17}\text {Ne},2\hbox {p}~^{16}\text {F})\hbox {X}$$ 12 C ( 17 Ne , 2 p 16 F ) X , $$^{12}\text {C}(^{17}\text {Ne},$$ 12 C ( 17 Ne , $$^{16}\text {F})\hbox {X}$$ 16 F ) X as well as $$^{1}\text {H}(^{17}\text {Ne},^{16}\text {F})\hbox {X}$$ 1 H ( 17 Ne , 16 F ) X (X-denotes undetected reaction products) reactions with $$^{16}\text {F}$$ 16 F in the ground and excited states were analysed. The longitudinal momentum distribution of $$^{16}{\textrm{F}}$$ 16 F and the correlations between the detached protons were studied. In the case of the carbon target, there is a significant deviation from the predictions of the eikonal model. The eikonal approximation was used to extract spectroscopic factor values $$\hbox {C}^2{\textrm{S}}$$ C 2 S . The experimental $$\hbox {C}^2\hbox {S}$$ C 2 S value obtained with C target is markedly lower than that for H target. This is interpreted as rescattering due to simultaneous nucleon knockout from both reaction partners, $$^{17}\text {Ne}$$ 17 Ne and $$^{12}\text {C}$$ 12 C .
