Abstract: | Wavefunctions for N1?3H configurations in 4He are calculated using NN → N1N transition potentials V and 3HN → N13H transition potentials from a two-nucleon exchange mechanism. The radial N1?3H momentum distributions peak at ~ fm?1 which is much lower than the short-ranged V. For (πN) S-wave isobars, e.g. N1(1535) and N1(1700), N1?3H probabilities are estimated to be ~2‰ each, while those for N1's in higher (πN) partial waves are much smaller. |
