The Isospin Dependence of Short Range Correlations through Inclusive Electron Scattering from 40Ca and 48Ca
- Univ. of Virginia, Charlottesville, VA (United States)
Short Range Correlations (SRCs) have been recognized as responsible for the high momentum tail of the nucleon momentum distribution in nuclei and are necessary to explain the missing nuclear strength in the mean field theory. One of the important questions about SRCs is their iso-spin dependence, yet unseen in inclusive scattering. An experiment (E08014) took place in Hall A at Jefferson Lab in Spring 2011 aimed to study SRCs. The inclusive electron scattering cross-sections from different nuclei including 2D, 3He, 4He, 12C, 40Ca and 48Ca were measured in kinematic region of (0.8 < Q2 < 2.8 GeV2) and (1 < xbj < 2) where SRCs are expected to be dominant (xbj = Q2/(2 m_p w), Q2 is the 4-momentum transfer square, and w is the transfer energy). The cross section ratios of 4He nuclei to 3He for xbj > 2 were used to search for the presence of 3N SRCs. The analysis herein focuses on the isospin dependence of SRCs using the cross section ratio per nucleon of 48Ca to 40Ca.
