Analytic structure of the amplitude of dt scattering near the elastic threshold
Karnakov B. M. , Mur V. D., Pozdnyakov S. G. , Popov V. S.
A model-independent description of dt and na scattering has been obtained by means of an effective-radius expansion. The fusion reaction Л-> na near the elastic threshold has also been obtained using an effective-radius expansion. The positions of the ^-matrix poles, which are associated with the existence of an 5 He* (3/2 +) resonance and with the Coulomb interaction, have been found.
