In the early stages of the burn of an inertial confinement fusion (ICF) target, the plasma parameter g can be greater than one, indicating that the number of electrons in a Debye cube is less than one. Under these conditions, the assumptions used in the classical plasma treatment are not valid. A fusion product slowing-down model is derived for strongly coupled non-classical plasmas and is compared with the classical slowing-down expression. A simple expression for interpolation between the classical region and the nonclassical region is proposed. The effect that this new slowing-down expression has on the burn of ICF targets is investigated in a companion paper.
