The Rate of the Proton-proton Reaction
We re-evaluate the nuclear matrix element for the proton-proton reaction p + p → H + e + νe, which is important for stellar-evolution calculations referring to stars with masses < ∼ 1M⊙ and for the solar-neutrino problem. We selfconsistently determine the effect of vacuum polarization on the matrix element by first correcting the low-energy scattering data to account for vacuum polarization. We...
متن کاملGravitational lensing and the proton - proton reaction
This article is a longer and more complete version of a comment I posted on Nature journal’s website. Go to the article “Supernova 'kaleidoscope' seen for first time” by Maggie McKee (http://www.nature.com/news/supernova-kaleidoscope-seen-for-first-time1.17062) and scroll way down the page to read it. So the best abstract I can think of is to reproduce that comment here. Is gravitational lensin...
متن کاملThe Electron-Screening Correction for the Proton-Proton Reaction
We test the Salpeter formalism for calculating electron screening of nuclear fusion reactions by solving numerically the relevant Schrodinger equation for the fundamental proton-proton reaction. We evaluate exactly the square of the overlap integral of the two-proton wave function and the deuteron wave function and compare with the usual analytic approximation. The usual WKB solution agrees wit...

We evaluate exactly the square of the overlap integral of the two-proton wave function and the deuteron wave function and compare with the usual analytic approximation. The usual WKB solution agrees with the numerical result to O(10). The...
متن کاملProton transfer dynamics of the reaction H3O
The proton transfer reaction of H3O 1 and NH3 was studied using the crossed molecular beam technique at relative energies of 0.41, 0.81, and 1.27 eV. At all three energies, the center-of-mass flux distribution of the product ion NH4 1 exhibits sharply asymmetry, and the maximum is close to the velocity and direction of the precursor ammonia beam. The reaction transforms almost all of the 1.69 e...
