Dense-plasma screening effects on the thermonuclear 3H(2H,n)4He fusion reaction

Abstract

We investigate the dense-plasma screening effects on the thermonuclear [Formula: see text] fusion reaction. In this study, we focus on the strong screening with the weak quantum effect in the thermonuclear region. At the first step, we calculate the cross-section and [Formula: see text]-factor of the bare [Formula: see text] fusion using a model inspired by halo/cluster effective field theory approach. The evaluations of the plasma screening corrections in the [Formula: see text]-factor and the reaction rate would be studied in the next step. Concentrating on the thermonuclear region, we use the Salpeter’s potential justifying the electron cloud around reactant as an incompressible and uniformly charged liquid drop. Finally, we show the changes in the [Formula: see text]-factor and production rate due to the screening electrons.
