A general formula for the differential cross section of this process was calculated by Elwert and Haug, who showed thatthe solution obtained in the relativistic limit using Born approximations by Bethe and Heitler was a special case of their formula.In Coulombic collisions, the radiation cross section for this process is proportional to the log of the ratio of maximumto minimum momentum transfers, while in the limit of low frequencies and small velocity changes, the intensity per unitfrequency for this process is proportional to the velocity change squared times the Lorentz gamma squared. A thermal formof this process in ionized HII regions results in free-free emission, and in cases where the acceleration is normal to the velocity,this process reduces to synchrotron radiation. For 10 points, identify this radiation which is emitted when particles undergorapid deceleration, such as when they impact a target.
