Core level binding energies for the elements Zr-Te (Z=40-52)

The binding energies of all core levels in the M and N shells for the elements Zr to Te (except Tc) the M V level of Y have been measured by means of ESCA. The binding energies obtained are compared to previously reported values. The Tc binding energies are estimated through an interpolation between the neighbouring elements. Also the M zeta X-ray energies for the elements Y to Rh are discussed in connection with the present results.
