Present day chiral nucleon-nucleon potentials up to next-to-next-tonext-to leading order and three nucleon forces at next-to-next-to leading order are used to analyze nucleon-deuteron radiative capture at deuteron laboratory energies below Ed ≈ 100 MeV. The differential cross section and the deuteron analyzing powers Ay(d) and Ayy are presented and compared to data. The theoretical predictions ...

If A q (β, α, k) is the scattering amplitude, corresponding to a potential q ∈ L 2 (D), where D ⊂ R 3 is a bounded domain, and e ikα·x is the incident plane wave, then we call the radiation pattern the function A(β) := A q (β, α, k), where the unit vector α, the incident direction, is fixed, and k > 0, the wavenumber, is fixed. It is shown that any function f (β) ∈ L 2 (S 2), where S 2 is the u...
