Popis:	The accuracy of spin-Hamiltonian determination via analysis of electron spin-echo nuclear modulation signals is investigated for F centers in KCl. It turns out that the accuracy matches that of ENDOR. The linewidth of the signals converted to the frequency domain also compares well with ENDOR. Parametric spectrum estimation with autoregressive modeling (maximum entropy method) yields significant further reduction of the linewidth. Analysis of the signal strength in the frequency domain appears feasible.
