Russia's Rosatom and China's Atomic Energy Authority (CAEA) have signed a Comprehensive Programme for Long-Term Cooperation in the field of fast-neutron reactors and closing the nuclear fuel cycle.
With major new investments in infrastructure for neutron science in the US, Europe, Asia, and Australia either completed or in advanced planning, our capabilities for understanding new materials using...
NEWPORT NEWS, VA, October 16, 2014 – Like dancers swirling on the dance floor with bystanders looking on, protons and neutrons that have briefly paired up in the nucleus have higher-average momentum, ...
Upper limits on the observational effects of nuclear pasta in neutron stars
relativity – gravitational waves – dense matter – stars neutron – stars
2011/7/21
The effects of the existence of exotic nuclear shapes at the bottom of the neutron star inner crust - nuclear `pasta' - on observational phenomena are estimated by comparing the limiting cases that th...
Oscillations of hot, young neutron stars: Gravitational wave frequencies and damping times
Oscillations of hot young neutron stars
2011/7/21
We study how the frequencies and damping times of oscillations of a newly born, hot proto-neutron star depend on the physical quantities which characterize the star quasi-stationary evolution which fo...
Relativistic separable interaction kernel of the neutron-proton system with inelasticities
neutron-proton system Relativistic separable interaction
2011/7/20
Within a covariant Bethe-Salpeter approach, the relativistic complex separable neutron-proton interaction kernel is proposed. The uncoupled partial-wave states with the total angular momentum $J$=0,1 ...

density matrix neutron drops
2011/7/20
Microscopic input to a universal nuclear energy density functional can be provided through the density matrix expansion (DME), which has recently been revived and improved.

neutron-neutron scattering length
2011/7/20
We compute a model-independent correlation between the difference of neutron-neutron and proton-proton scattering lengths |a(nn)-a^C(pp)| and the splitting in binding energies between Helium-3 and tri...

Periodic Box FHNC calculations neutron star crustal matter
2011/7/20
Neutron star crustal matter, whose properties are relevant in many models aimed at explaining observed astrophysical phenomena, has so far always been studied using a mean field approach. In order to ...

Fast Neutron Detection 6Li-loaded Liquid Scintillator
2011/7/21
We report on the development of a fast neutron detector using a liquid scintillator doped with enriched Li-6. The lithium was introduced in the form of an aqueous LiCl micro-emulsion with a di-isoprop...
