…elementary area is E, the flux through the element is defined as the product of the magnitude dS and the component of E normal to the element—i.e., the scalar product E · dS. A charge q at the centre of a sphere of radius r generates a field ε =…

…rich in chlorine atoms, the flux from the boron-8 (8B) source of solar neutrinos can convert a few of the chlorine-37 (37Cl) atoms to argon-37 (37Ar) atoms with a half-life of 35 days. These atoms can then be detected by nuclear decay counting to determine the flux of the high-energy…
