$η$ photoproduction on the quasi-free nucleons in the chiral quark model
chiral quark model quasi-free nucleons
2011/7/20
A chiral quark-model approach is adopted to study the $\eta$ photoproduction off the quasi-free neutron and proton from a deuteron target. Good descriptions of the differential cross sections, total c...

Limit on Lorentz and CPT violation of the bound Neutron Using a Free Precession 3He/129Xe co-magnetometer
Lorentz CPT violation of the bound Neutron Free Precession 3He/129Xe co-magnetometer
2010/12/20
We report on the search for Lorentz violating sidereal variations of the frequency difference of colocated spin-species while the Earth and hence the laboratory reference frame rotates with respect to...
Hadro- and photo-production of η' in quasi-free proton and neutron processes
η′ production free and quasi-free photoproduction meson production in NN collisions
2009/11/24
The η' photoproduction process on quasi-free proton and neutron and the reaction NN→η′NN are investigated within a relativistic effective Lagrangian approach to hadronic interactions. Resonances with ...
Africa Renounces Nukes--Treaty's Entry Into Force Makes Entire Southern Hemisphere Free of Nuclear Weapons
Africa Southern Hemisphere Nuclear Weapons
2009/8/17
A Treaty making Africa into a zone free of nuclear weapons entered into force on 15 July 2009, in turn expanding the nuclear-weapon free territories to cover the entire Southern hemisphere. The Treaty...
Heavy ion reactions producing a heavier deformed nucleus and free nucleons
Fission reactions charged particle induced fission mulifragmentation 12C + 197Au reactions calculated angular distributions and variances
2010/4/8
Carbon induced heavy ion reactions on the heavy 197Au target are considered. The statistical scission model is used to calculate this fission process. In the present considered reactions, the process ...
