neutron capture cross section table

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.

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%

an experimental (n,γ) cross section is reported for the first time. The results are compared with the ENDF, EAF, and TENDL evaluations. Maxwellian-averaged cross sections were also calculated using the same input γSF and LD functions. DOI: 10.1103/PhysRevC.101.014619 I. INTRODUCTION Neutron-capture reactions play a critical role in a variety

If neutron absorption leads to radioactivity, column four lists its half-life. Usually, this activity is caused by radiative capture of neutrons; in those few

significant change of the capture cross section of 207Pb from 0.712 ± 0.012 b to 0.620 ± 0.014 b is particularly important, because this cross section is utilized as a standard in thermal neutron capture cross section measurements by the method of prompt gamma rays produced by the capture of thermal neutrons.

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 cross section is not in general equal to the actual area of the nucleus. For instance the radiative capture cross section for Au197 at the peak of 4.9 eV resonance is 3x10-20 2cm , whereas the geometrical area of its nucleus is just 1.938x10-24 cm2. The reaction cross section is much greater than the physical cross section of the nucleus
