Abstract
Many nuclear isomers were produced in the past by irradiating the appropriate ground state isotope with a broad spectrum high energy x-ray machine. It is proposed to use the known cross sections of the above photoexcitation processes to measure the spectral intensity of the high current pulsed x-ray machines with Mev end points. By using this technique each x-ray pulse can be analyzed separately. Isotopes of Ir, Ag, Se, In, Br, Sr and Cd are shown to be suitable for spectral range of 600 keV - 1300 keV.
