“…Note that this sharply decaying spectral strength is at odds with calculations employing traditional phenomenological NN forces, which typically populate these offshell regions with higher probabilities [57,76]. Off-shell high-energy components are observed in electron-scattering experiments [77] and may provide a way to quantify the short-range component of NN forces [78].…”

I review the application of self-consistent Green's function methods to study the properties of infinite nuclear systems. Improvements over the last decade, including the consistent treatment of three-nucleon forces and the development of extrapolation methods from finite to zero temperature, have allowed for realistic predictions of the equation of state of infinite symmetric, asymmetric and neutron matter based on chiral interactions. Microscopic properties, like momentum distributions or spectral functions, are also accessible. Using an indicative set of results based on a subset of chiral interactions, I summarize here the first-principles description of infinite nuclear systems provided by Green's function techniques, in the context of several issues of relevance for nuclear theory including, but not limited to, the role of short-range correlations in nuclear systems, nuclear phase transitions and the isospin dependence of nuclear observables.

“…If the high-momentum proton and neutron densities are equal in both 3 He and 3 H, this trend could result from SCX processes which would increase the 3 Heðe; e 0 pÞ cross section, but decrease the 3 Hðe; e 0 pÞ cross section. While further calculations are needed to fully quantify this effect, this equal-density assumption is supported both by ab initio calculations [53] and by previous measurements that showed that, at high p miss , electrons scatter primarily off nucleons in np-short-range correlated pairs [54][55][56][57][58][59][60][61][62][63][64]. We can test this, since SCX effects should be suppressed in isoscalar systems due to large cancellations between ðn; pÞ and ðp; nÞ processes.…”

“…In the range 300 MeV/c < P miss < 600 MeV/c pn-pairs were found to be around 20 times more prevalent in 12 C than pp-or nn-pairs [73], which points to a predominantly tensor character of the probed N N-interaction [74]. However, other measurements [75] showed that the np-dominance decreases towards larger P miss , which can be explained by a transition from a spindependent (tensor) to a spin-independent (scalar) regime of the N N-interaction at high momenta.…”

Quasi-free scattering in inverse kinematics as a tool to unveil the structure of nuclei

2021

View full text Add to dashboard Cite

Quasi-free scattering of electrons and protons has been extensively utilized in the past to study the single-particle structure of nuclei, clustering in light nuclei, and short-range correlated nucleon–nucleon pairs in nuclei. Recently, this approach has been applied in inverse kinematics using hydrogen targets. The characteristic features of this reaction and the experimental challenges and advantages of inverse-kinematics experiments are summarized. The applicability to radioactive beams opens a large research potential to study a variety of properties of neutron-to-proton asymmetric nuclei. Applications of quasi-free scattering in inverse kinematics and its potential are reviewed based on recent and ongoing research programs at different accelerator facilities worldwide.
