  We investigate iterated Tikhonov methods coupled with a Kaczmarz strategy for
obtaining stable solutions of nonlinear systems of ill-posed operator
equations. We show that the proposed method is a convergent regularization
method. In the case of noisy data we propose a modification, the so called
loping iterated Tikhonov-Kaczmarz method, where a sequence of relaxation
parameters is introduced and a different stopping rule is used. Convergence
analysis for this method is also provided.
