angles such that 2ka sin-1 (14.112) If the frequency is low enough so that ka o 1,
then the limit qa & 1 will apply at all angles. But for frequencies where ka » 1,
there will be a region of forward angles less than 0.-4 (14.113) ka where the limit

15.5 Radiation cross section So in the complete screening limit. The constant
value is the semiclassical result. The curve marked O (4) “Bethe-Heitler” is the
quantummax (A) mechanical Born approximation. For extremely relativistic
particles ...
