Neutron Activation Cross Section of Molybdenum Isotopes at 14.8 MeV

抄録

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 ²⁷Al (a, a) ²⁴Na and the ²⁷Al (n, p) ²⁷Mg reactions. The cyclic activation method was employed for the T-ray measurement of short-lived nuclei. A 55 cm³ Ge (Li) detector was used for the measurement of r-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.
