In this paper, we study the simplified generalized Gauss–Newton method in a Hilbert scale setting to get an approximate solution of the ill-posed operator equation of the form F(x)=y where F:D(F)XY is a nonlinear operator between Hilbert spaces X and Y. Under suitable nonlinearly conditions on F, we obtain an order optimal error estimate under the Morozov type stopping rule.

Keywords: Nonlinear Ill-Posed Operator Equations; Iterative Regularization Methods; Hilbert Scale, Stopping Index
