Description
We use the linear response theory to describe the inter-nuclear potential in dense early Universe
e ̄e-pair plasma. We account for nuclear motion perturbing plasma as a function of time. Prior
efforts are improved by inclusion of moving screening charge scattering in the dense plasma medium
and quantitative evaluation of the governing collision damping rate. We asses the influence of these
new dynamical screening effects on the thermonuclear BBN reaction rates
