Development of active neutron nondestructive assay system [PDF]
EPJ Web of ConferencesThe assay of Special Nuclear Materials (SNM) and Minor Actinides (MA) in highly-radioactive nuclear materials poses a significant challenge for nuclear non-proliferation and security. No single nondestructive method can provide acceptable and practicable

Retrieval of electron-atom scattering cross sections from laser-induced electron rescattering of atomic negative ions in intense laser fields [PDF]
, 2007 We investigated the two-dimensional electron momentum distributions of atomic negative ions in an intense laser field by solving the time-dependent Schrodinger equation (TDSE) and using the first- and 2nd-order strong-field approximations (SFA).

Atomic Scale Sliding and Rolling of Carbon Nanotubes [PDF]
, 1999 A carbon nanotube is an ideal object for understanding the atomic scale aspects of interface interaction and friction. Using molecular statics and dynamics methods different types of motion of nanotubes on a graphite surface are investigated.

Evaluation of important phenomena through the PIRT process for a sodium fire event
Nihon Kikai Gakkai ronbunshu, 2020 Sodium fire is one of key issues in sodium-cooled fast reactor (SFR) plants. JAEA has developed sodium fire analysis codes, a zone model code SPHINCS and a field model code AQUA-SF, to evaluate the consequence of sodium fire events.

Machine-learning of atomic-scale properties based on physical principles
, 2019 We briefly summarize the kernel regression approach, as used recently in materials modelling, to fitting functions, particularly potential energy surfaces, and highlight how the linear algebra framework can be used to both predict and train from linear ...

Neutrino scattering on atomic electrons in searches for neutrino magnetic moment
, 2010 The scattering of a neutrino on atomic electrons is considered in the situation where the energy transferred to the electrons is comparable to the characteristic atomic energies, as relevant to the current experimental search for neutrino magnetic moment.
