New $^3$He Elastic Cross Section Measurements and Global Fits

ORAL

Abstract

Mining data from Jefferson Lab Hall A experiment E08-014, a new measurement of the $^3$He elastic cross section at Q$^2 \approx $ 35 fm$^{-2}$ was extracted. This new data point falls approximately halfway between the first and second diffractive minima of the $^3$He charge form factor. This point's location, along with other recent $^3$He elastic cross section measurements, fill out a previously understudied kinematic region. The new data make an improved fit of the $^3$He elastic cross section world data possible. This presentation will discuss the new cross section measurement and fits in comparison to previous fit results and current theoretical predictions.
