The effect of nucleon's possible quark-diquark structure is added to the usual constituent quark model to calculate nucleon's charge root-mean-square radius. The experimental values of both 1/2 =(0.88±0.03) fm for a proton and 1/2 =(0.12±0.01) fm 2 for a neutron are reproduced ...
Re-examines the determination of the root-mean square radius of the deuteron (rd) from the appropriate experimentally determined electric form factors, GEd, GEp, GEd/GEp and GEn. With a particular extrapolation of results from realistic NN interactions and a specific assumption regarding the shape ...

The calculation of root mean square nuclear charge radius is one of the most important nuclear parameters regarding the size and structure of the nucleus. In this paper calculations for root mean square (r.m.s.) radius of the ground state of 6Li nucleus using high energy electron scattering ...
Monoatomic gases helium (He), argon (Ar), and xenon (Xe) are isolated from the atmosphere and placed in the same tank. How does the root-mean-square speed vary between these three species? 4PRACTICE PROBLEM A 0.15m long cube filled with nitrogen (N2, molar mass 28.01 g/mol) at...
A point always moves in a direction that is tangent to its path; for a circular path, for example, its direction at any instant is perpendicular to a line from the point to the centre of the circle (a radius). The magnitude of the velocity (i.e., the speed) is the time rate at...
charge radius.We report the results of root mean square (r.m.s.) radii of heavy flavoured mesons in a QCD model with the potential V ( r )=(4 伪 s /3 r ) + b r + c . As the potential is not analytically solvable, we first obtain the results in the absence of confinement ...
