Overview

E12-011-112 (x>1) at Hall A is proposed to precisely measure the isospin dependence of two-nucleon short range correlations using mirror nuclei 3H and 3He. More details can be found in the PAC38 Proposal and Patricia's web page.


Run Periods

Fall 2018

  • Beam energy: 5 pass for optics, 2 pass for production.
  • [Run plan]
  • Surveys:
