We consider light scattering by uniform spheres of arbitrary size R and refractive index m. A new internal coupling parameter rho' = 2kR vertical bar(m(2) - 1)/(m(2) + 2)vertical bar where k = 2 pi/lambda and lambda is the wavelength is proposed that has a superior ability to determine the asymptotic regimes of small size, weakly refractive and large size, refractive than the parameter rho = 2kR(m - 1). It also has superior ability as a parameter to organize patterns in light scattering from spheres.
