Weak capture of protons by protons
The cross section for the proton weak capture reaction H(p,eνe) H is calculated with wave functions obtained from a number of modern, realistic high-precision interactions. To minimize the uncertainty in the axial two-body current operator, its matrix element has been adjusted to reproduce the measured Gamow-Teller matrix element of tritium β decay in model calculations using trinucleon wave fu...
متن کاملRadiative capture of neutrons by protons
A model-independent irreducible tensor approach to p(n, γ)d is presented and an explicit form for the spin-structure of the matrix M for the reaction is obtained in terms of the Pauli spin-matrices σ(n) and σ(p). Expressing the multipole amplitudes in terms of the triplet → triplet and singlet → triplet transitions, we point out how the initial singlet and triplet contributions to the different...
متن کاملTheory of Scattering of Protons by Protons
quantitatively in agreement, as regards 'magnitudes, variation with angle, and variation with voltage, with a simple phase shift of the spherically symmetrical de Broglie wave ("S wave") due to the collision or scattering, corresponding to a new attractive force overpowering the Coulomb repulsion, and give a rather accurate measure of the "potential well" which is therefore permissible as repre...
متن کاملAnalysis of the antineutrino capture on protons
Corrections to the zeroth-approximation cross-section formula for antineutrino capture on protons at nuclear reactors are evaluated. They include recoil corrections 1 I M of three kinds. The true recoil correction to the cross section is negligible. The weak-magnetism-axial-vector interference is sizable, decreasing the cross section by -2% for 5-MeV positrons. One also has to include the recoi...
متن کاملPotentiation of TRPC5 by protons.
Mammalian members of the classical transient receptor potential channel subfamily (TRPC) are Ca(2+)-permeable cation channels involved in receptor-mediated increases in intracellular Ca(2+). TRPC4 and TRPC5 form a group within the TRPC subfamily and are activated in a phospholipase C-dependent manner by an unidentified messenger. Unlike most other Ca(2+)-permeable channels, TRPC4 and -5 are pot...
