Therefore, a particular neutron capture cross section not Table 1. Parameters for the simulation of the neutron spectra with PINO [11]. Proton energy.

The resonance neutron capture cross section of /sup 89/Y has been measured between 2.5 and 100 keV with the neutron capture facility at the 40-m flight station on the Oak Ridge Electron Linear Accelerator. Resonance parameters were extracted for levels below 50-keV bombarding energy.

The Atlas of Neutron Capture Cross Sections (NGATLAS) contains cross sections data of neutron induced reactions for targets up to, and including, curium (Z=96). It comprises 739 target isotopes with half-lives above 0.5 day. Cross sections to ground, first and second isomers are listed separately.

The neutron capture cross sections of {sup 114}Sn, {sup 115}Sn, {sup 116}Sn, {sup 117}Sn, {sup 118}Sn, and {sup 120}Sn were measured in the energy range from 3 to 225 keV at the Karlsruhe 3.75 MV Van de Graaff accelerator. Neutrons were produced via the {sup 7}Li({ital p},{ital n}){sup 7}Be reaction using a pulsed proton beam.

The advantage of using heavy water for neutron moderation is that its low thermal neutron capture cross section ( (th), Table 19.3) improves the neutron economy (i.e. 1 - p becomes much less than in LWRs) so that even natural uranium can be used as fuel.

Abstract. lead isotopes were obtained at the Oak Ridge electron linear accelerator, in th e neutron energy range above 2.5 keV. These were analyzed for cluded in a new evaluation of lead cross

The thermal neutron capture cross sections (GO) and the resonance integrals (Io) of some fission products (FP), such as 137Cs, ^Sr, wTc, 129I and 135Cs, were measured by the activation and y-ray spectroscopic methods. Moreover, the cross section measurements were done for other FP elements, such as I27I, 133Cs arid I34Cs. This paper provides

Neutron capture and total cross sections of 155Gd and 157Gd were measured with the neutron time-of-flight method in Accurate Neutron-Nucleus Reaction measurement Instrument at Material and Life Science Experimental Facility of the Japan Proton Accelerator Research Complex using the NaI (Tl) spectrometer and Li-glass detectors.

scenario, lead to its release in the environment during long-term storage. But, after neutron capture, 99Tc becomes 100Tc, decaying to the stable isotope 100Ru with a half-life of 16 s. Therefore, 99Tc is a very good candidate for transmutation. Several measurements of the neutron cross sections of 99Tc have been performed in the past [1-5]

Among the significant findings are the following. The neutron width of the largest resonance in Gd, at 0.032 eV in 157Gd, has been measured to be (9 6 1)% smaller than that given in ENDF/B-VI updated through release 8. The thermal (2200 m/s) capture cross section of157Gd has been measured to be 11%

The neutron capture cross sections of 1 7 5 Lu and 1 7 6 Lu have been measured in the energy range from 3 to 225 keV at the Karlsruhe 3.7 MV Van de Graaff accelerator.
