Dynamic Screening and Thermonuclear Reaction Rates
We show that there are no dynamic screening corrections to the Salpeter’s enhancement factor in the weak-screening limit. Subject headings: nuclear reactions
متن کاملScreening in Thermonuclear Reaction Rates in the Sun
We evaluate the effect of electrostatic screening by ions and electrons on low-Z thermonuclear reactions in the sun. We use a mean field formalism and calculate the electron density of the screening cloud using the appropriate density matrix equation of quantum statistical mechanics. Because of well understood physical effects that are included for the first time in our treatment, the calculate...
متن کاملPrediction of Thermonuclear Reaction Rates in Astrophysics
Recent improvements and remaining problems in the prediction of thermonuclear rates are reviewed. The main emphasis is on statistical model calculations, but the challenge to include direct reactions close to the driplines is also briefly addressed. Further theoretical as well as experimental investigations are motivated.
متن کاملSolar models and NACRE thermonuclear reaction rates
Using the most recent updated physics, calibrated solar models have been computed with the new thermonuclear reaction rates of NACRE, the recently available European compilation. Comparisons with models computed with the reaction rates of Caughlan & Fowler (1988) and of Adelberger et al. (1998) are made for global structure, expected neutrinos fluxes, chemical composition and sound speed profil...
متن کاملThermonuclear rates of the 28Si(p, y) reaction
2014 The 28Si(p, y) reaction data have been analysed in terms of two alternative versions of the directsemidirect model. The extrapolation of the theoretical excitation functions has been made and the astrophysical S-factor has been extracted with no significant differences between the predictions of the models. The analysis reveals the dominant role of the nonresonant process at temperatures l...
