Title: Systematic Measurement of keV-neutron Capture Cross Sections and Capture Gamma-ray Spectra of Sn Isotopes

Abstract

The capture cross sections and capture {gamma}-ray spectra of 117,119Sn were measured in an incident neutron energy region from 10 to 100 keV and at 570 keV, using a 1.5-ns pulsed neutron source by the 7Li(p,n)7Be reaction and a large anti-Compton NaI(Tl) {gamma}-ray spectrometer. A pulse-height weighting technique was applied to observed capture {gamma}-ray pulse-height spectra to derive capture yields. The capture cross sections of 117,119Sn were obtained with the error of about 5% by using the standard capture cross sections of 197Au. The present cross sections were compared with previous experimental data and the evaluated values in JENDL-3.3 and ENDF/B-VI. The capture {gamma}-ray spectra of 117,119Sn were derived by unfolding the observed capture {gamma}-ray pulse-height spectra.

  • The capture cross sections of 92Zr were measured in the incident neutron energy region from 15 to 90 keV and at 550 keV. A neutron time-of-flight method was adopted with a ns-pulsed neutron source by the 7Li(p,n)7Be reaction and with a large anti-Compton NaI(Tl) spectrometer. A pulse-height weighting technique was applied to observed capture gamma-ray pulse-height spectra to derive capture yields. Using the standard capture cross sections of 197Au in ENDF/B-VI, the capture cross sections of 92Zr were obtained with the errors from 7% to 11%. The present results were compared with previous measurements and the evaluations of JENDL-3.3 andmore » ENDF/B-VI. The capture gamma-ray spectra of 92Zr were derived by unfolding observed capture gamma-ray pulse-height spectra.« less
  • The keV-neutron capture cross section and capture {gamma}-ray spectra of nuclides with a neutron magic number N= 82, {sup 139}La and {sup 142}Nd, were newly measured by the time-of-flight method. Capture {gamma}-rays were detected with an anti-Compton NaI(T1) spectrometer, and the pulse-height weighting technique was applied to derive the neutron capture cross section. The results were provided with our previous measurements of other nuclides around N= 82, {sup 140}Ce, {sup 141}Pr, {sup 143}Nd and {sup 145}Nd.
  • The neutron absorption and fission cross sections for $sup 239$Pu and $sup 235$U have been measured over the neutron energy range from 0.02 eV to 200 keV. In addition, the neutron capture cross section for $sup 197$Au was measured from 10 to 50 keV and the fission cross section of $sup 233$U was measured from 0.1 to 100 keV. Normalization of the $sup 239$Pu and $sup 235$U data was made over the energy region from 0.02 to 0.4 eV to the ENDF/B-III neutron cross sections for these isotopes, Mat 1159 and 1157, respectively. The capture cross section for $sup 197$Aumore » was normalized using the saturated resonance method for the 4.9-eV resonance. For $sup 233$U fission, the normalization was made using the results of Weston et al. The neutron flux was measured using the $sup 10$B(n,$alpha$) reaction; the energy variation used for this reaction was that given in ENDF/B-III. A large liquid scintillator about 40 m from the neutron source was used to detect the prompt gamma-ray cascades resulting from neutron absorption in the sample. In general for $sup 239$Pu and $sup 235$U, these experiments indicated lower neutron fission cross sections than contained in ENDF/ B-III for energies above 10 keV. The measured values of the ratio $alpha$, neutron capture-to-neutron fission, for $sup 239$Pu agree within errors with those derived from ENDF/B-III, Mat 1159. For the present measurements, the uncertainty on $alpha$ for $sup 239$Pu is approximately 11 percent at 10 keV and increases to approximately 30 percent at 100 keV. The experimental results for the neutron capture cross section for $sup 197$Au are approximately 15 percent lower than the ENDF/B-III values. The measurements of the ratio of the neutron fission cross section for $sup 233$U to that for $sup 235$U are generally higher than the ENDF/B-III values by approximately 5 percent. 15 tables, 11 figures.

  • Photoneutron cross sections were measured for {sup 96}Zr near neutron threshold with quasimonochromatic laser-Compton-scattering {gamma}-ray beams. A systematic analysis of photoneutron and radiative neutron capture data for zirconium isotopes within the statistical model calculation leads to a unified picture of low-energy {gamma}-ray strengths for zirconium isotopes that is described by the HFB + QRPA model of E1 strength supplemented with an extra {gamma} strength attributed to a giant M1 resonance. Results of the systematic analysis including radiative neutron capture cross sections for radioactive {sup 95}Zr and {sup 93}Zr nuclei are presented.
