Abstract:The amplitude of the primordial magnetic field (PMF) is constrained from observational limits on primordial nuclear abundances. Within this constraint, it is possible that nuclear motion is regulated by Coulomb scattering with electrons and positrons (e ± 's), while e ± 's are affected by a PMF rather than collisions. For example, at a temperature of 10 9 K, thermal nuclei typically experience ∼ 10 21 scatterings per second that are dominated by very small angle scattering leading to minuscule changes in the n… Show more
