Results of electron-induced one- and two-nucleon hard knockout reactions,$A(e,e'p)$ and $A(e,e'pN)$, in kinematics sensitive to nuclear short-rangecorrelations, are studied using the nuclear contact formalism. A relationbetween the spectral function and the nuclear contacts is derived and used toanalyze the dependence of the data on the initial energy and momentum of theknocked-out proton. The ratio between the number of emitted proton-proton pairsand proton-neutron pairs is shown to depend predominantly on a single ratio ofcontacts. This ratio is expected to present a deep minima in the initial energyand momentum plane, associated with the node in the proton-proton wavefunction. The formalism is applied to analyze data from recent $^4$He and$^{12}$C electron-scattering experiments performed at Jefferson laboratory.Different nucleon-nucleon potentials were used to asses the model-dependence ofthe results. For the ratio of proton-proton to proton-neutron pairs in $^4$He,a fair agreement with the experimental data is obtained using the twopotentials, whereas for the ratio of proton-proton pairs to the totalknocked-out protons in $^{12}$C, some of the features of the theory are notseen in the experimental data. Several possible explanations for thisdisagreement are discussed. It is also observed that the spectral function atspecific domains of the momentum-energy plane is sensitive to thenucleon-nucleon interaction. Based on this sensitivity, it might be possible toconstrain the short range part of the nuclear potential using such experimentaldata.
