Cross Section
<math>\frac{d^{3}\sigma}{d \omega d\Omega} = \frac {N_{cut}}{(Q/e).LT. \epsilon .A. \chi . \Delta E' . \Delta . \Omega}</math>
NCut = Numbers of electrons that pass good electron cuts
Q/e = Number of beam electrons
LT = live time
π = Detector efficiencies
A = Acceptance (SAMC)
π = effective target thickness (sigma/cos(th) -g/cm2)
βEβ = Scattered electron momentum bin size
βπΊ = Solid angle
Results:
Acceptance applied cross sections : [[1]]
