    • Abstract

       

      Cross-sections for the reactions Mo92 (n, p) Nb92, Mo95 (n, p) Nb95 and Mo96 (n, p) Nb96 in natural molybdenum irradiated in the reactor “Apsara”, are calculated from thick target yield measurements. The reaction Ni58 (n, p) Co58 was used as the standard for the measurement. The activities of the niobium isotopes, chemically separated from the target, are measured by taking the photopeak of the characteristicγ-ray of each isotope using a scintillation spectrometer. These activities are then compared with the standard. Possible sources of error in the measurement are discussed.
