Two ty pes of functions used to describe the electromagnetic structure of nucleon s include &ldquo\;form factors&rdquo\;\, which describe the spatial distri bution of charge and magnetism within the nucleon\, and &ldquo\;structure functions&rdquo\;\, which describe their longitudinal momentum distributio n. We explore form factors by exclusive scattering of high energy leptons with the nucleus or focusing on elastic channels in our analysis\; we expl ore structure functions by inclusive scattering with the nucleus. When exp loring the electromagnetic structure of the neutron\, 3He is a n ideal target for quasi-elastic scattering because the proton-proton wave -function is dominated by the spin-zero\, S-state (by approximately 90%). Thus\, scattering leptons from a polarized 3He target is a rea sonable approximation to scattering from a polarized\, free neutron.
\n\nMy talk will focus on the polarizable 3H
e targets used in two experiments at Jefferson National Laboratory: one ex
periment explores the neutron electric form factor\, GE­\;<
/span>n\, and the other experim
ent explores the neutron structure function\, A1n.
I will discuss my work in the filling and characterization of these target
s as well as optimizing these targets for future experiments at higher bea
m energies.
