Comparing Simulated and Measured 3He Neutron-to-Proton Knockout Ratios

ORAL

Abstract

Short-range correlated (SRC) pairs of nucleons provide a valuable setting for studying the short-range regime of the NN interaction due to their close proximity and high relative momentum. The relative abundance of neutrons and protons in SRC pairs has been studied with electron scattering as a function of nuclear size and asymmetry for several different nuclear targets, but few measurements have been made with direct neutron detection. Recent data mining analyses from the CLAS experiment at Jefferson Lab have identified neutrons from the hard break up of SRC pairs. Here these techniques are applied to data on light nuclei and used to benchmark few-body calculations.  This talk will present 3He(e,e'n)/3He(e,e'p) ratios in the CLAS experiment at Jefferson Lab, both in the mean field and in the short-range correlated pair regime. Simultaneously, we compare the experimental result with theoretical predictions in the Plane-Wave Impulse Approximation using the spectral functions of Ciofi degli Atti and Kaptari.
