A semiempirical model for generating molybdenum target x‐ray spectra is presented. The model is an extension of a previous model developed by the authors for tungsten and takes into account the depth of production for both bremsstrahlung and characteristic x‐ray photons. As in the previous work, the optimal model parameters were determined using nonlinear least‐squares fits to experimental data. Good agreement between the two was obtained. By varying target angle, off‐axis angle, and filtration in the model in accordance with the x‐ray tube and geometry of interest, results consistent with tabulated spectra for different conditions have been obtained.
