Neutron Activation Cross Section of Molybdenum Isotopes at 14.8 MeV

Abstract

Abstract The neutron activation cross sections of Mo isotopes have been measured for the 14.8 MeV neutron. The cross sections have been determined with reference to the known 27A1 (n, α)24Na and the 27Al(n, p)27Mg reactions. The cyclic activation method was employed for the γ-ray measurement of short-lived nuclei. A 55 cm3 Ge(Li) detector was used for the measurement of γ-ray spectra. Cross section data are presented for (n, 2n), (n, p) and (n, a) reactions on Mo isotopes. The cross sections of (n, np) reactions on 98Mo are also presented. The exponential dependence on (N-Z)/A of the (n, p) reaction cross sections are discussed.
