Cross-section calculations of photofission reactions for 238,239,240,241,242,244Pu isotopes using nuclear level density [PDF]

open access: yesЯдерна фізика та енергетика, 2022
Photofission cross-sections of 238,239,240,241,242,244Pu isotopes are theoretically investigated with the collective semi-classical Fermi gas model (CSCFGM) by using Talys computer code in the energy range 1 - 30 MeV.

Web Tool for Constructing a Covariance Matrix from EXFOR Uncertainties

open access: yesEPJ Web of Conferences, 2012
The experimental nuclear reaction database EXFOR contains almost no covariance data because most experimentalists provide experimental data only with uncertainties.

A COMPARISON OF OXIDE DECAY HEAT SIMULATIONS AND NUCLEAR DATA LIBRARIES WITH FUSION IRRADIATION EXPERIMENTS [PDF]

open access: yesEPJ Web of Conferences, 2021
We compare existing experimental decay heat data sets measured at the JAEA fusion neutron source (FNS), which employed a fast extraction rabbit system that in certain cases allowed the measurements to capture, at short cooling times, the decay profile of

Evaluation of  99Mo and  99mTc Productions Based on a High‐Performance Cyclotron

open access: yesScience and Technology of Nuclear Installations, Volume 2013, Issue 1, 2013., 2013
Following preliminary feasibility studies which started at Legnaro National Laboratories (LNL) in 2011, the Italian National Institute for Nuclear Physics (INFN) research activities are underway aiming at the alternative, accelerator‐driven, 99Mo/ 99mTc production routes.

Model calculations for cosmogenic nuclides in meteorites and the lunar surface. 1. Long‐lived radionuclides

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 4, Page 600-620, April 2026.
Abstract Production rates for the cosmogenic radionuclides 10Be, 14C, 26Al, 36Cl, 41Ca, 53Mn, and 60Fe in a large variety of meteorites, that is, ordinary chondrites (H, L, LL), carbonaceous chondrites, HED meteorites, ureilites, Martian meteorites, and iron meteorites and in the uppermost ~2 m of the lunar surface are modeled.

Landscape patterns drive provision of nature's contributions to people by mobile species

open access: yesJournal of Applied Ecology, Volume 61, Issue 11, Page 2666-2678, November 2024.
Our novel approach for spatial prediction can be applied to any of nature's contributions to people (NCP), and extended to identify trade‐offs and synergies among multiple NCP. For example, the negative NCP of possum density trades off with multiple known positive NCP from indigenous forests, including culturally significant non‐material NCP, and ...
