Radiative Neutron Capture on Lithium-7

The radiative neutron capture on lithium-7 is calculated model independently using a low energy halo effective field theory. The cross section is expressed in terms of scattering parameters directly related to the S-matrix element. The cross section depends on the poorly known p-wave effective range parameter r1. This constitutes the leading order uncertainty in traditional model calculations. ...

Radiative neutron capture on a proton at BBN energies

The total cross section for radiative neutron capture on a proton, np → dγ, is evaluated at big bang nucleosynthesis (BBN) energies. The electromagnetic transition amplitudes are calculated up to next-to leading order within the framework of pionless effective field theory with dibaryon fields. We also calculate the dγ → np cross section and the photon analyzing power for the d~γ → np process f...

Model-independent calculation of radiative neutron capture on lithium-7.

The radiative neutron capture on lithium-7 is calculated model independently using a low-energy halo effective field theory. The cross section is expressed in terms of scattering parameters directly related to the S-matrix elements. It depends on the poorly known p-wave effective range parameter r(1). This constitutes the largest uncertainty in traditional model calculations. It is explicitly d...

Radiative neutron-proton capture in effective chiral Lagrangians.

We calculate the cross-section for the thermal n+ p → d+ γ process in chiral perturbation theory to next-to-next-to-leading order using heavy-fermion formalism. The exchange current correction is found to be (4.5 ± 0.3) % in amplitude and the chiral perturbation at one-loop order gives the cross section σ th = (334 ± 2) mb which is in agreement with the experimental value (334.2 ± 0.5) mb. Toge...

Λ-Neutron Scattering Lengths from Radiative K− Capture

Radiative capture of the K by the deuteron is examined as a reaction for measurement of the Λ-neutron scattering lengths. Using the final state interaction, analogous to measurements of the radiative capture of pions by deuterium, the scattering lengths of both the triplet and singlet Λ-n interaction can be inferred. The problem of the separation of these two fundamental parameters without and ...
