Abstract
The cross section of neutron-deuteron radiative capture is calculated at energies relevant to Big-Bang nucleosynthesis ( Kev) with pionless Effective Field Theory. At these energies, magnetic transition M1 gives the dominant contribution. The M1 amplitude is calculated up to next-to-next-to leading order(NLO) with insertion of three-body force. Results are in good agreement within few percent theoretical uncertainty in comparison with available calculated data below E=200 Kev.
