Description
The enhancement factor to the thermonuclear reaction rate in the center
of the Sun is calculated using the Feynman-Kac path integral of the
grand-canonical partition function. Using the generalized virial
expansion for a multicomponent quantum plasma, we have calculated the
truncated pair distribution function for solar conditions up to the
order ρ5/2 in density. The enhancement factor is
calculated for the p - p channel. This result extends the well-known
Salpeter calculation of the enhancement factor in the classical limit
and exhibits the various classical and quantum corrections beyond the
Debye-Hückel screening correction. In this issue, it comes out that
quantum corrective terms related to the statistics are the leading
corrections beyond the Salpeter's result. Indeed, this result can induce
significant changes in the prediction of solar neutrino deficit.
