Dynamic breaking of a single gold bond [PDF]

, 2017
While one might assume that the force to break a chemical bond gives a measure of the bond strength, this intuition is misleading. If the force is loaded slowly, thermal fluctuations may break the bond before it is maximally stretched, and the breaking ...

Role of the total isospin 3/2 component in three-nucleon reactions [PDF]

, 2016
We discuss the role of the three-nucleon isospin T=3/2 amplitude in elastic neutron-deuteron scattering and in the deuteron breakup reaction. The contribution of this amplitude originates from charge-independence breaking of the nucleon-nucleon potential

Charge-Independence Breaking in the Two-Pion-Exchange Nucleon-Nucleon Force [PDF]

, 1999
Charge-independence breaking due to the pion-mass difference in the (chiral) two-pion-exchange nucleon-nucleon force is investigated. A general argument based on symmetries is presented that relates the charge-symmetric part of that force to the proton ...

Influence of Kind of Weft Yarn on Properties of the Seersucker Woven Fabrics

AUTEX Research Journal, 2016
Seersucker woven fabrics create a unique 3D woven structure. Such 3D structure is usually received on loom by an application of two warps of different tension. However, a kind of the weft yarn also significantly influences the structure and properties of
