Phys. Rev. C 66, 055801 (2002) [5 pages]Radiation correction to astrophysical fusion reactions and the electron screening problemReceived 18 August 2002; published 6 November 2002 We discuss the effect of electromagnetic environment on laboratory measurements of the nuclear fusion reactions of astrophysical interest. The radiation field is eliminated using the path integral formalism in order to obtain the influence functional, which we evaluate in the semiclassical approximation. We show that enhancement of the tunneling probability due to the radiation correction is extremely small and does not resolve the longstanding problem that the observed electron screening effect is significantly larger than theoretical predictions. © 2002 The American Physical Society URL:
