“…In our energy intervals 10 ≤ E p ≤ 49 MeV and 13 ≤ E d ≤ 31 MeV both the proton and deuteron energy distributions, S(E p ) and S(E d ), obtained via the impulse approximation model and the realistic wave functions for the 3 He nucleus ground state [45,47,48,50] can be well described by the expression…”

“…Other points indicating the importance and the necessity of studying processes of muon capture by 3 He nuclei are the following: -Progress in the wave function calculations for the initial and final states of such a three-body system [47,48,49,50,51,52] will give a better comparison between experiment and theory.…”

“…Since it was first possible to perform rigorous nd scattering calculations [1] it has been known that the nucleon vector analyzing power A y cannot be described by any realistic nucleon-nucleon (NN) force at energies below ≈ 30 MeV. The same is true for the deuteron vector analyzing power iT 11 , whereas the deuteron tensor analyzing powers and the differential cross section, for example, can be described very well.…”

The nucleon-deuteron analyzing power A y in elastic nucleon-deuteron scattering poses a longstanding puzzle. At energies E lab below approximately 30MeV A y cannot be described by any realistic NN force. The inclusion of existing three-nucleon forces does not improve the situation. Because of recent questions about the 3 P J NN phases, we examine whether reasonable changes in the NN force can resolve the puzzle. In order to do this we investigate the effect on the 3 P J waves produced by changes in different parts of the potential (viz., the central force, tensor force, etc.), as well as on the 2-body observables and on A y . We find that it is not possible with reasonable changes in the NN potential to increase the 3-body A y and at the same time to keep the 2-body observables unchanged. We therefore conclude that the A y puzzle is likely to be solved by new three-nucleon forces, such as those of spin-orbit type, whichhave not yet been taken into account.PACS numbers:

“…Faddeev methods have already been used with success in the study of three-nucleon reactions [25,26], but variational methods are the best available for the study of four-nucleon reactions at present. Our initial studies have been of the electroweak capture reactions: 2H(d,y)4He below 500 keV c.m.…”
