Investigation of the Exclusive ^{3}He(e,e'pn)p Reaction

TL;DR

This paper reports the first measurements of the ^{3}He(e,e'pn)p reaction cross sections at specific energy transfers and momentum transfers, comparing experimental data with theoretical calculations.

Contribution

It provides new experimental data on the ^{3}He(e,e'pn)p reaction and evaluates the accuracy of continuum Faddeev calculations with different nucleon-nucleon potentials.

Findings

Measured cross sections at 220 and 270 MeV energy transfers.

Faddeev calculations overestimate data at low recoil momentum.

Discrepancy between theory and experiment decreases at higher recoil momentum.

Abstract

Cross sections for the ^{3}He(e,e'pn)p reaction were measured for the first time at energy transfers of 220 and 270 MeV for several momentum transfers ranging from 300 to 450 MeV/c. Cross sections are presented as a function of the momentum of the recoil proton and the momentum transfer. Continuum Faddeev calculations using the Argonne V18 and Bonn-B nucleon-nucleon potentials overestimate the measured cross sections by a factor 5 at low recoil proton momentum with the discrepancy becoming much smaller at higher recoil momentum.
