P_11 Resonance Extracted from pi-N Data and Its Stability
pN scattering amplitude analysis Roper resonance
2011/7/20
We study the stability of resonance poles in pi-N P_11 partial wave, particularly the Roper resonance, by varying parameters significantly within the EBAC dynamical coupled-channels model, keeping a g...
Stability of fragments and study of participant-spectator matter at peak center-of-mass energy
center-of-mass energy participant-spectator matter
2011/7/20
We simulate the central reactions of nearly symmetric, and asymmetric systems, for the energies at which the maximum production of IMFs occurs (E$_{c.m.}^{peak}$).This study is carried out by using ha...

Phase stability and structural temperature dependence in sodium niobate: A high resolution powder neutron diffraction study
Phase stability structural temperature dependence high resolution powder neutron diffraction
2010/11/24
We report investigation of structural phase transitions in technologically important material sodium niobate as a function of temperature on heating over 300-1075 K. Our high resolution powder neutron...
Pt-Decorated PdCo@Pd/C Core-Shell Nanoparticles with Enhanced Stability and Electrocatalytic Activity for Oxygen Reduction Reaction
Core-Shell Nanoparticles Enhanced Stability Electrocatalytic Activity Oxygen Reduction Reaction
2010/11/25
The high cost and scarcity of Pt pose serious problems for the widespread commercialization of fuel cell technologics.1 Recently, Pd-based cathode catalysts have attracted much attention because Pd po...
Nuclear physics gets a stepping stone to the 'island of stability'（图）
Nuclear physics a stepping stone the 'island of stability'
2010/2/23
Researchers in Europe have made a key breakthrough in fundamental nuclear physics by making the first direct mass measurement of an element heavier than uranium. They say that their new technique will...
