A theory is derived for the effect of the elementary processes on the superheating-ionization instability in a gas discharge with a rotating electric field E. The rotation of the vector E in a cone with vertex angle theta, corresponding to sin/sup 2/theta=2/3, reduces the instability growth rate by a factor of three as compared with a static field. If dissociative attachment is important in the electron balance (in which case the logarithmic derivative of the attachment coefficient with respect to the electron temperature is a large, positive quantity) then rotation in a plane or a rocking of the vector E can suppress the instability. The detachment process substantially reduces the effectiveness of stabilization by planar rotation.
