This expansion allows an evaluation of the mixing parameter εBB from a knowledge of the deuteron asymptotic D to S ratio, pion mass and other low-energy observables, such as the scattering lengths, deuteron binding etc., of the nucleon-nucleon system. We demonstrate that the correct long range behavior of the tensor potential is essential for a realistic reproduction of εBB.14-18engArtigo10.1016/0370-2693(93)91775-IWOS:A1993MH90900003Acesso restrito2-s2.0-000246032686212588459563480000-0002-2811-9797[4]
