| Title | A=3 (e,e') xB=1 cross-section ratios and the isospin structure of short-range correlations | ||||
| Abstract | We study the relation between measured high-xB, high-Q2, Helium-3 to Tritium, (e,e?) inclusive-scattering cross-section ratios and the relative abundance of high-momentum neutron-proton (np) and proton-proton (pp) short-range correlated (SRC) nucleon pairs in three-body (A=3) nuclei. Analysis of this data using a simple pair-counting cross-section model suggested a much smaller np/pp ratio than previously measured in heavier nuclei, questioning our understanding of A=3 nuclei and, by extension, all other nuclei. Here we examine this finding using spectral-function-based cross-section calculations, with both an \textit{ab initio} A=3 spectral function and effective Generalized Contact Formalism (GCF) spectral functions using different nucleon-nucleon interaction models. The \textit{ab initio} calculation agrees with the data, showing good understanding of the structure of A=3 nuclei. An 8\% uncertainty on the simple pair-counting model, as implied by the difference between it and the \t | ||||
