The deuteron pole in the nucleon-nucleon scattering amplitude

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

This paper deals with the deuteron as a bound state ia nucleon-nucleon scattering. The coupled Z=0 andl=2 amplitudes of the J=1, I=0NN state have been treated within the framework of relativistic partial-wave dispersion relations using the matrix extension of theN/D technique in order to solve the coupled integral equations. As left-hand singularities we take into account the contributions of one-boson-exchange terms. Furthermore, the triplet scattering length is introduced as a subtraction constant.

Riassunto

In questo articolo si tratta del deutone come stato legato nello scattering nucleonenucleone. Si sono trattate le ampiezze relativistiche accoppiatel=0 ed l=2 dello statoNN, J=1, I=0 nello schema delle relazioni di dispersione dell’onda parziale, facendo uso dell’estensione matriciale della tecnicaN/D per risolvere le equazioni integrali accoppiate. Come singolarità a sinistra si tiene conto dei contributi dei termini di scambio di un bosone. Inoltre si introduce la lunghezza di scattering del tripletto come costante di sottrazione.
