This article is a continuation of our previous work (Phys. Rev. A 88, 032511(2013)). The prefactors for the partial-wave expansion of the helium atom arederived. Due to series of cancellations, the partial-wave increments of theenergy converge as $L^{-2N-6}$. The origin of these cancellations is identifiedfrom alternative expressions of the partial-wave energies. There is someevidence that the assumptions of regularities for the exact wavefunction can bereduced.
