Evaluations of the characteristics of the radionuclides Cm, Cm, Cm, and Cm obtained from data published up to 2013 are presented. A computer program is developed for constructing and visualizing the decay schemes of radionuclides and is used to determine the decay schemes for these curium isotopes. [ABSTRACT FROM AUTHOR]

The current status of some decay data used in nuclear astrophysics and cosmochronology is presented. The half-life of Se has been evaluated as 3.6(3) × 10 yr. The total energy of non-neutrino radiation released in act of Ar decay has been obtained being 2.709 (16) keV per disintegration. The recommended half-life values of the long-lived radionuclides ( T ≳ 10 yr) of Al, K, Mn, Fe, Rb, Zr, Tc, Pd, I, Cs, Sm, Lu, Hf, Re, Pb, Th, U, U, Pu, and Cm are given based on the evaluations published until 2010.

New estimated values of the decay and radiation characteristics of the radionuclides 233Th, 239U, 236Np, 236 mNp, 238Np, and 239Np obtained in light of information published in 2009 are presented. [ABSTRACT FROM AUTHOR]

Methods and procedures for monitoring the consistency of sets of recommended data for radioactive nuclide decay characteristics are considered. A procedure is proposed, which combines three methods of checking the consistency of quantities related to the decay scheme of a radionuclide: the decay energy, the energies and probabilities of nuclear transitions, the internal conversion coefficients and the energies and emission probabilities of the radiations accompanying the decay.

The decay data evaluation results are presented for the 242Cm and 244Cm radionuclides decaying to the levels in 238Pu and 240Pu, respectively. The evaluated data have been obtained using information published up to 2005. [ABSTRACT FROM AUTHOR]

High quality nuclear data is the most fundamental underpinning for all neutron metrology applications. This paper describes the release of version II of the International Reactor Dosimetry and Fusion File (IRDFF-II) that contains a consistent set of nuclear data for fission and fusion neutron metrology applications up to 60 MeV neutron energy. The library is intended to support: a) applications in research reactors; b) safety and regulatory applications in the nuclear power generation in commercial fission reactors; and c) material damage studies in support of the research and development of advanced fusion concepts. The paper describes the contents of the library, documents the thorough verification process used in its preparation, and provides an extensive set of validation data gathered from a wide range of neutron benchmark fields. The new IRDFF-II library includes 119 metrology reactions, four cover material reactions to support self-shielding corrections, five metrology metrics used by the dosimetry community, and cumulative fission products yields for seven fission products in three different neutron energy regions. In support of characterizing the measurement of the residual nuclei from the dosimetry reactions and the fission product decay modes, the present document lists the recommended decay data, particle emission energies and probabilities for 68 activation products. It also includes neutron spectral characterization data for 29 neutron benchmark fields for the validation of the library contents. Additional six reference fields were assessed (four from plutonium critical assemblies, two measured fields for thermal-neutron induced fission on 233U and 239Pu targets) but not used for validation due to systematic discrepancies in C/E reaction rate values or lack of reaction-rate experimental data. Another ten analytical functions are included that can be useful for calculating average cross sections, average energy, thermal spectrum average cross sections and resonance integrals. The IRDFF-II library and comprehensive documentation is available online at www.nds.iaea.org/IRDFF/. Evaluated cross sections can be compared with experimental data and other evaluations at www.nds.iaea.org/exfor/endf.htm. The new library is expected to become the international reference in neutron metrology for multiple applications. [ABSTRACT FROM AUTHOR]
