N2 - We calculate the exact shape of the enhanced coherent backscattering peak for electrons in the presence of an external magnetic field. The interference phenomena that cause the backscattered enhancement are reduced due to the breaking of time-reversal symmetry. It is shown that the form of the peak in the presence of a magnetics field I(q,H) can be obtained (to a good approximation) from I(q,H=0) by replacing q with qI=[q2+(3LH2)-1]11, where LH=(2Latin small letter h with strokec/eH)1/2. We have also calculated I(q,H) at finite temperatures and proposed it as the most sensitive tool for extracting inelastic processes.
