“…The discrete level scheme in TALYS is based on the discrete level file of Belgya, as stored in the Reference Input Parameter Library (RIPL-3) database [58,83]. RIPL-3 contains the known level schemes and electromagnetic and γ -ray decay probabilities, which were compiled and available from the Evaluated Nuclear Structure Data File (ENSDF) in October 2007 [84]. For higher excitation energies, where discrete level information is not available or incomplete, nuclear level densities are used.…”

Pomp, S. (2018). First isomeric yield ratio measurements by direct ion counting and implications for the angular momentum of the primary fission fragments. Physical Review C, 98 (2) We report the first experimental determination of independent isomeric yield ratios using direct ion counting with a Penning trap, which offered such a high resolution in mass that isomeric states could be separated. The measurements were performed at the Ion Guide Isotope Separator On-Line (IGISOL) facility at the University of Jyväskylä. The isomer production ratios of 81 Moreover, based on the isomeric yield ratios, the root-mean-square angular momenta (J rms ) of the fission fragments after scission were estimated using the TALYS code. The experimentally determined isomeric yield ratios, and consequently the deduced J rms , for 130 Sn are significantly lower compared to 128 Sn for both fissioning systems. This can be attributed to the more spherical shape of the fragments that contribute to the formation of 130 Sn, due to their proximity to the N = 82 shell closure. The values of J rms for 129 Sb are higher than 128 Sn for both reactions, despite the same neutron number of both nuclides (N = 78), indicating the odd-Z effect where fission fragments with odd-Z number tend to bear larger angular momentum than even-Z fragments. The isomer production ratio for the isotopes of Sn is more enhanced in the nat U(p, f ) reaction than in 232 Th(p, f ). The opposite is observed for 96 Y and 97 Y. These discrepancies might be associated to different scission shapes of the fragments for the two fission reactions, indicating the impact that the different fission modes can have on the isomeric yield ratios.

“…Modern evaluations, from either DDEP (Decay Data Evaluation Project [1]) or ENSDF (Evaluated Nuclear Structure Data File [2]) provide spectrally integrated emission quantities determined using the LogFT program [3]. For various applications, users now require lower uncertainties than those present in current nuclear databases, as well as the full beta and neutrino spectra.…”

Abstract. The new code BetaShape has been developed in order to improve the nuclear data related to beta decays. An analytical model was considered, except for the relativistic electron wave functions, for ensuring fast calculations. Output quantities are mean energies, log f t values and beta and neutrino spectra for single and multiple transitions. The uncertainties from the input parameters, read from an ENSDF file, are propagated. A database of experimental shape factors is included. A comparison over the entire ENSDF database with the standard code currently used in nuclear data evaluations shows consistent results for the vast majority of the transitions and highlights the improvements that can be expected with the use of BetaShape.

“…Thus, the recommended data and decay scheme relative to a nuclide, and information concerning the way the evaluation was achieved, are available as PDF files. Decay data are also available in the ENSDF file format [2] and as a simple text file. A specific PenNuc text file, intended to be used for Penelope Monte Carlo simulation, has recently been added that describes the complete decay scheme of a nuclide to be used as a radioactive source in a simulation process.…”

Abstract. As a primary laboratory in the field of ionising radiation metrology, the Laboratoire National Henri Becquerel (LNE-LNHB), CEA Saclay, is involved in measurements, evaluations and dissemination of radioactive decay data.Data measurements undertaken by various laboratories are evaluated by an international commission of experts (Decay Data Evaluation Project) coordinated by LNHB staff in order to establish a set of recommended decay scheme data.New nuclide evaluations are regularly added to our website, the NUCLÉIDE database, published in the BIPM-5 Monographie series and uploaded to our web application LARAWEB, a dedicated tool for alpha and gamma spectrometry. The Mini Table of Radionuclides is produced from time-to-time with data extracted from our database.Various publications are described, along with new search criteria and decay scheme visualisation in LARAWEB.
