In dense astrophysical plasmas, neutron capture populates highly excitednuclear states close to the neutron threshold. The impact of additionallow-energy nuclear excitations via coupling to the atomic shell on the abilityof the so-formed compound nucleus to retain the captured neutron isinvestigated. We focus on the mechanism of nuclear excitation by electroncapture in plasmas characterized by electron fluxes typical for the slowneutron capture process of stellar nucleosynthesis. The small effect of thisfurther excitation on the neutron capture and gamma decay sequence relevant fornucleosynthesis is quantified and compared to the corresponding effect of anadditional low-energy photoexcitation step.
