The isospin dependence of Short Range Correlations through Inclusive Electron Scattering from ⁴⁰Ca and ⁴⁸Ca

Short Range Correlations (SRCs) have been recognized as responsible for the high momentum tail of the nucleon momentum distribution, n(k). Interactions of 2N pairs are responsible for the high momentum tail and these additionally imprint a universal character on n(k) for all nuclei at large momentum, k. One of the important outstanding questions about SRCs is their isospin dependence, yet unseen in inclusive scattering. An experiment (E08014) took place in Hall A at Jefferson Lab in Spring 2011 and measured inclusive electron scattering cross-sections from the Ca isotopes (⁴⁰Ca and ⁴⁸Ca). By taking the ratio of the per nucleon cross section of ⁴⁸Ca to ⁴⁰Ca in a kinematic region dominated by SRCs we are able to extract their isospin dependence. After a brief introduction to the theory and the established experimental character of SRCs, the results of the cross-section ratio of ⁴⁸Ca to ⁴⁰Ca will be presented.
