Die2H+d-Reaktion bei niedrigen Energien

It is shown that in the angular distributions of the²H(d, p)³H (using polarized and unpolarized deuterons) and likewise in the neutron polarization of the mirror reaction²H(d, n)³He the resonance found atE _d ≈105 keV can be understood as a threshold resonance. From the experimental dataJ)^π=2⁽⁺⁾,T=0 is derived for spin, parity and isospin of the resonance. Additionally it is found, that the resonant part of the reaction has a small coupling matrix element, linking the²H+d channel with the³H+p and³He+n channels.
