The reaction 7Li(p,n)7Be has been widely used as neutron source in various experiments for astrophysical and technological applications. Since its neutron energy spectrum resembles a Maxwell-Boltzmann distribution around kT= 25 keV for incident proton energies of 1912 keV and for a proper irradiation geometry, it is specially suited for studying neutron capture reactions of interest for the...

A challenging task within the modelling of new generation reactor neutron kinetics is the calculation of the gamma-heat deposition e.g. in steel and ceramics reflectors without UO2 blankets, which is required to be known with an uncertainty as low as 7.5%. A major difficulty in measuring the competition between neutron and gamma-ray emission during fission fragment de-excitation is the...

At IRMM and PTB, several 235U and 238U parallel-plate fission ionization chambers are employed as reference instruments for measuring the spectral neutron fluence in monoenergetic as well as ‘white’ neutron beams with energies up to 200 MeV. Some of these instruments were already manufactured more than 20 years ago. Therefore a comparison exercise was organized at the PTB ion accelerator...

The first results from a new program of experiments to measure nuclear level densities in the actinide region will be presented. This series of measurements has three important goals: 1) To provide systematic level density information for improving cross section calculations where direct measurements are difficult or impossible. 2) The simultaneous measurements of compound nuclear decay...

Improvement on nuclear data has received a special attention in the last decades within the framework of “Technology Advances in Fast Reactors and Accelerator Driven System for Actinides and Long-Lived Fission Products Transmutation”. Neutron cross section (capture, fission, inelastic) data for minor actinides (MA), as well as delayed neutron data and decay heat data with improved accuracy...

In this contribution the efforts made to improve procedures for the analysis of cross section data in the resonance region, both resolved and unresolved, will be reported. The activities have been performed within the EFNUDAT project.
To improve the quality of the resonance parameters deduced from high resolution time-of-flight cross section data two new features have been implemented in the...
