K X-ray emission spectra of Ti, V, Cr and Mn generated by photon excitation have been studied with a crystal spectrometer. The measured energy shifts of K$_{\alpha}$ satellite relative to the diagram line are compared with values obtained by electron excitation and with different theoretical estimates. The present experimental values of K$_{\alpha}$L1/K$_{\alpha}$L0 relative intensities are compared with values obtained by electron excitation.
