Recall also that the relativistic beam is not required for the wave excitation under these experimental conditions: [V.sub.[perpendicular to]0 [approximately equal to] 0.08c.
Though the relativistic beam is not needed for the XASW excitation, the demands on the external magnetic field appear rigid enough to realize the conditions of the excitation.
