Description
One major goal of the Low Energy Recoil Tracker (ALERT) experimental program at the Thomas Jefferson National Accelerator Facility (JLab) is to study the fundamental structure of nucleons bound in a Helium-4 nucleus. This study explores the transition of strongly bound neutrons to the first excited state of the nucleon known as the Delta resonance. The excitation is induced by scattering electrons off a liquid Helium-4 target. By measuring the scattered electron, along with the decay products of the Delta and the recoiling Helium-3 nucleus, a fully inclusive analysis of the reaction can be performed and comparisons can be made of the transition form factors to previous quasi-free measurements. The N-Delta transition form factors provide a quantitative description of how the charge and magnetization are distributed within the particles involved, and this study will shed light on how those distributions may differ for a nucleon strongly bound inside a nucleus versus an unbound nucleon. A discussion of the progress on Monte Carlo simulations on Monte that lay the groundwork for analysis of data has been presented here.
