Abstract
The
fusion cross-sections show a resonant behavior
down to the lowest energies accessible so far in the laboratory. If
this tendency continues into the astrophysical energy range, the stellar
reaction rates have to be corrected for resonant
screening effects, in addition to the conventional screening
corrections. We estimate the resonant screening effects in the weak
electron screening limit for hydrostatic burning and
white-dwarf environments.
