The KADoNiS project is an online database for cross sections relevant to the s process and p process.The respective s-process library provided on this webpage is an updated sequel of the well-established Bao et al. Cross-sections are used to express the likelihood of particular interaction between an incident neutron and a target nucleus. The most recent evaluations were completed in 2005 and a report was published in 2007 (STI/PUB/1291). The dosimetry community requires covariances for the full energy range from 10-5 eV to 20 MeV for their evaluations. Currently, we are using the fast-neutron flux-weighted partial γ-ray cross section from ENDF/B-VII.1 for the production of the 847-keV 2 1 + → 0 + gs transition in 56 Fe, σ γ … More information is provided in each of the following Books: neutron (175 MiB) gamma (5.29 MiB) proton (15.1 MiB) deuteron (5.00 MiB) triton (904 KiB) 4. This evaluation has been supported by the Working Party on International Evaluation Cooperation (WPEC), the Cross Section Evaluation Working Group (CSEWG), and an International Atomic Energy Agency Coordinated Research Program (CRP). Back to the Collision cross sections for ions of many small molecules, peptides, denatured proteins, native-like proteins, and native-like protein complexes are reported below. Nuclear properties, evaluations, cross section plotting Nuclear Data Validation Group: Application Code Libraries : ACE-format, MATXS-format, COVFIL-format, SCALE: Table of γ-rays: Decay diagram Electron and Photon Attenuation: Electron stopping powers, photon attenuation coefficients PEARL (Photonic Electronic Atomic Reaction Laboratory) Microscopic Cross-section. For energy dependent complete list of elements and isotopes is also available. 3, No. Not many cross sections can be obtained absolutely - most cross sections are measured relative to the cross section standards and converted using evaluations of the standards. Custom 2D and 3D plots of the incident-neutron data can be made using the Nuclear Data Viewer.Select the types ENDFB-VII.1-neutron for raw ENDF/B-VII.1 evaluations or ENDF-VII.1-neutron-pointwise for files with reconstructed resonance cross sections and other information added by NJOY processing. The most recent evaluations were completed in 2005 and a report was published in 2007 (STI/PUB/1291). We recently updated our Collision Cross Section Database. Unfortunately many of the 'standards' were not appropriate. Numerical values of (n,g) cross sections are available for a total of 739 targets for the elements H (Z=1, A=1) to Cm (Z=96, A=248) totaling 972 reactions. 3, No. Please fill out the following information: Help Charged-particle cross section database for medical radioisotope production (IAEA/NDS) Nuclear Data for Charged Particle Activation (CPA) compiled by Karel Strijckmans Neutron source reactions: DROSG-2000: Neutron Source Reactions by M.

This is an index to the contents of the new ENDF/B-VII.1 library of evaluated incident-neutron data. Not many cross sections can be defined as absolute - most are measured relative to the cross section standards. For energy dependent cross sections please go to the National Nuclear Data Center at Brookhaven National Lab. Experts in data evaluation and in the Numerical values of (n,g) cross sections are available for a total of 739 targets for the elements H (Z=1, A=1) to Cm (Z=96, A=248) totaling 972 reactions. The units of the macroscopic cross section are cm-1 (i.e., cm2/cm3). Many of the standards are used directly in neutron dosimetry for fluence determination. some errors may exist. The neutron total cross section is determined by measuring the transmitted neutron spectrum through the sample and comparing the incident neutron spectrum. . Nuclear Data Center at Brookhaven National Lab. All of this data was taken from the Special Feature section of neutron scattering lengths and cross sections of the elements and their isotopes in Neutron News , Vol. 29-37.

Custom 2D and 3D plots of the incident-neutron data can be made using the Nuclear Data Viewer.Select the types ENDFB-VII.1-neutron for raw ENDF/B-VII.1 evaluations or ENDF-VII.1-neutron-pointwise for files with reconstructed resonance cross sections and other information added by NJOY processing. If you need to cite this page, you can copy this text: Kenneth Barbalace. JANIS Books are available for nuclear reactions induced by neutrons, photons and light-charged particles. The library contains neutron cross section data for 58 reactions used for reactor dosimetry by foil activation. Not many cross sections can be defined as absolute - most are measured relative to the cross section standards. 29-37. 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). The data is in ENDF-6 format, processed into 640 group structure. And in some cases, improved candidates were suggested [ CAR70 , CIE77 ] but not adopted, largely as a result of the need to significantly improve their databases which would have required significant effort.
