Atomic electron tomography in three and four dimensions [PDF]

, 2020
Atomic electron tomography (AET) has become a powerful tool for atomic-scale structural characterization in three and four dimensions. It provides the ability to correlate structures and properties of materials at the single-atom level.

State- and event-based refinement [PDF]

, 2006
In this paper we give simple example abstract data types, with atomic operations, that are related by data refinement under a definition used widely in the literature, but these abstract data types are not related by singleton failure refinement.

Evaluations and calculations of neutron reactions on 238U up to 20 MeV

Nuclear Engineering and Technology
In order to improve the quality of neutron data for 238U in CENDL, considering the impact of new measurements, a brand-new evaluation of the complete set of neutron induced 238U reaction data up to 20 MeV has been performed. Important reactions, such as (

Study of the Spin-Memory Effect with low-energy gamma-rays in 177Hf(n,γ)178Hf reaction measurement [PDF]

EPJ Web of Conferences
A method on the basis of the Spin-Memory Effect (SME) is available to measure the total angular momentum J of a resonance in a neutron capture reaction. This method uses the fact that the intensity ratio of two gamma-rays emitted from a resonance depends

Nuclear effects in atomic transitions

, 2010
Atomic electrons are sensitive to the properties of the nucleus they are bound to, such as nuclear mass, charge distribution, spin, magnetization distribution, or even excited level scheme.

A stress test on 235U(n, f) in adjustment with HCI and HMI benchmarks

EPJ Web of Conferences, 2017
To understand how compensation errors occur in a nuclear data adjustment mostly devoted to U-Pu fuelled fast critical experiments and with only limited information on U-235 data, a stress test on 235U(n,f) was suggested, using critical benchmarks ...
