Radiative neutron capture on carbon14 in effective field theory
Abstract
The cross section for radiative capture of neutron on carbon14 is calculated using the modelindependent formalism of halo effective field theory. The dominant contribution from E1 transition is considered, and the cross section is expressed in terms of elasticscattering parameters of the effectiverange expansion. Contributions from both resonant and nonresonant interaction are calculated. Significant interference between these leads to a capture contribution that deviates from a simple BreitWigner resonance form.
