They begin by looking at the fundamentals of collision theory both classical and quantum mechanically for the case of potential scattering
, namely one channel.
Experimental evidence (e.g., impulse response of a flat plate) indicates that edges are a major potential scattering
source of stealth objects after the typical ones such as specular reflection, cavity or ducting scattering, and angular scattering are effectively controlled .
In the case of using a SG apparatus to measure the spin, the proton is intact both before and after the measurement, potential scattering
being by definition elastic.
Neglecting the small potential scattering
of the neutrons with spin component parallel to the [.sup.3]He nuclear spin ([sigma] [up arrow][up arrow] [barn] [approximately equal to] 5), the transmission [T.sub.[+ or -]] for both spin orientations through a cell with polarized [.sup.3]He is given by
