Cross-section measurements for reactions on platinum isotopes induced by neutron beams in energy range of 13.5 to 14.6MeV

Cross-sections for (n,2n) and (n,p) reactions have been measured on platinum isotopes at the neutron energies of 13.5 to 14.6 MeV using the activation technique. Data were reported for the following reactions: Pt-198(n,2n) (197m)+g Pt, Pt-198( n, 2n) (197)m, Pt-192(n, 2n) Pt-191, Pt-194(n, P) Ir-194, Pt-195(n, p) Ir-195m, and (196)pt( n, P) (196)m Ir. At the neutron energies of 13.5, 14. 1 and 14.6 MeV, the cross sections in mb are 2038 +/- 159, 1919 +/- 73 and 1836 +/- 68 for Pt-198(n,2n) (197m+g) Pt reaction; 974 +/- 37, 1055 +/- 39 and 1042 +/- 39 for R-198(n,2n) (197m) Pt reaction, respectively. The cross sections are 1680 +/- 103, 1810 +/- 67 and 2047 +/- 97 for Pt-192(n,2n) Pt-191 reaction, and 1.0 +/- 0.2, 1.6 +/- 0.2 and 1.8 +/- 0.2 for Pt-195( n, P) Ir-195m reaction, respectively, at energies of 14.1, 14.4 and 14.6 MeV. At 14.1 and 14.4 MeV neutron energies, the cross sections are 3.8 +/- 0.4 and 5.4 +/- 0.5 for Pt-194(n, p) Ir-194 reaction. While, the data are (1.13 +/- 0.07) and (1.18 +/- 0.06) mb at energies of 13.5 and 14. 4 MeV, respectively, for Pt-196(n, P) Ir-196 reaction. The neutron fluences were determined using the monitor reaction Nb-93(n, 2n)Nb-92m or Al-27(n,a)Na-24. A comparison was made between the present cross sections and the collected data for the measured reactions.
